+   Programs that use <stdbool.h> should be aware of some limitations
+   and standards compliance issues.
+
+   Standards compliance:
+
+       - <stdbool.h> must be #included before 'bool', 'false', 'true'
+         can be used.
+
+       - You cannot assume that sizeof (bool) == 1.
+
+       - Programs should not undefine the macros bool, true, and false,
+         as C99 lists that as an "obsolescent feature".
+
+   Limitations of this substitute, when used in a C89 environment:
+
+       - <stdbool.h> must be #included before the '_Bool' type can be used.
+
+       - You cannot assume that _Bool is a typedef; it might be a macro.
+
+       - Bit-fields of type 'bool' are not supported.  Portable code
+         should use 'unsigned int foo : 1;' rather than 'bool foo : 1;'.
+
+       - In C99, casts and automatic conversions to '_Bool' or 'bool' are
+         performed in such a way that every nonzero value gets converted
+         to 'true', and zero gets converted to 'false'.  This doesn't work
+         with this substitute.  With this substitute, only the values 0 and 1
+         give the expected result when converted to _Bool' or 'bool'.
+
+   Also, it is suggested that programs use 'bool' rather than '_Bool';
+   this isn't required, but 'bool' is more common.  */

+                      r[n+j]:=r[n+j]-u.

+dnl
+dnl PRAGMA_SYSTEM_HEADER can be used in files that contain #include_next,
+dnl so as to avoid GCC warnings when the gcc option -pedantic is used.
+dnl '#pragma GCC system_header' has the same effect as if the file was found
+dnl through the include search path specified with '-isystem' options (as

+dnl does not warn about some things, and on some systems (Solaris and Interix)
+dnl __STDC__ evaluates to 0 instead of to 1. The latter is an undesired side

+dnl that contains a configuration script generated by Autoconf, under

+
+dnl This file defines some "once only" variants of standard autoconf macros.
+dnl   AC_CHECK_HEADERS_ONCE          like  AC_CHECK_HEADERS
+dnl   AC_CHECK_FUNCS_ONCE            like  AC_CHECK_FUNCS
+dnl   AC_CHECK_DECLS_ONCE            like  AC_CHECK_DECLS
+dnl   AC_REQUIRE([AC_FUNC_STRCOLL])  like  AC_FUNC_STRCOLL
+dnl The advantage is that the check for each of the headers/functions/decls
+dnl will be put only once into the 'configure' file. It keeps the size of
+dnl the 'configure' file down, and avoids redundant output when 'configure'
+dnl is run.
+dnl The drawback is that the checks cannot be conditionalized. If you write
+dnl   if some_condition; then gl_CHECK_HEADERS(stdlib.h); fi
+dnl inside an AC_DEFUNed function, the gl_CHECK_HEADERS macro call expands to
+dnl empty, and the check will be inserted before the body of the AC_DEFUNed
+dnl function.
+
+dnl The original code implemented AC_CHECK_HEADERS_ONCE and AC_CHECK_FUNCS_ONCE
+dnl in terms of AC_DEFUN and AC_REQUIRE. This implementation uses diversions to
+dnl named sections DEFAULTS and INIT_PREPARE in order to check all requested
+dnl headers at once, thus reducing the size of 'configure'. It is known to work
+dnl with autoconf 2.57..2.62 at least . The size reduction is ca. 9%.
+
+dnl Autoconf version 2.59 plus gnulib is required; this file is not needed
+dnl with Autoconf 2.60 or greater. But note that autoconf's implementation of
+dnl AC_CHECK_DECLS_ONCE expects a comma-separated list of symbols as first
+dnl argument!

+
+/* Each of these macros verifies that its argument R is nonzero.  To
+   be portable, R should be an integer constant expression.  Unlike
+   assert (R), there is no run-time overhead.
+
+   There are two macros, since no single macro can be used in all
+   contexts in C.  verify_true (R) is for scalar contexts, including
+   integer constant expression contexts.  verify (R) is for declaration
+   contexts, e.g., the top level.
+
+   Symbols ending in "__" are private to this header.
+
+   The code below uses several ideas.
+
+   * The first step is ((R) ? 1 : -1).  Given an expression R, of
+     integral or boolean or floating-point type, this yields an
+     expression of integral type, whose value is later verified to be
+     constant and nonnegative.
+
+   * Next this expression W is wrapped in a type
+     struct verify_type__ { unsigned int verify_error_if_negative_size__: W; }.
+     If W is negative, this yields a compile-time error.  No compiler can
+     deal with a bit-field of negative size.
+
+     One might think that an array size check would have the same
+     effect, that is, that the type struct { unsigned int dummy[W]; }
+     would work as well.  However, inside a function, some compilers
+     (such as C++ compilers and GNU C) allow local parameters and
+     variables inside array size expressions.  With these compilers,
+     an array size check would not properly diagnose this misuse of
+     the verify macro:
+
+       void function (int n) { verify (n < 0); }
+
+   * For the verify macro, the struct verify_type__ will need to
+     somehow be embedded into a declaration.  To be portable, this
+     declaration must declare an object, a constant, a function, or a
+     typedef name.  If the declared entity uses the type directly,
+     such as in
+
+       struct dummy {...};
+       typedef struct {...} dummy;
+       extern struct {...} *dummy;
+       extern void dummy (struct {...} *);
+       extern struct {...} *dummy (void);
+
+     two uses of the verify macro would yield colliding declarations
+     if the entity names are not disambiguated.  A workaround is to
+     attach the current line number to the entity name:
+
+       #define GL_CONCAT0(x, y) x##y
+       #define GL_CONCAT(x, y) GL_CONCAT0 (x, y)
+       extern struct {...} * GL_CONCAT(dummy,__LINE__);
+
+     But this has the problem that two invocations of verify from
+     within the same macro would collide, since the __LINE__ value
+     would be the same for both invocations.
+
+     A solution is to use the sizeof operator.  It yields a number,
+     getting rid of the identity of the type.  Declarations like
+
+       extern int dummy [sizeof (struct {...})];
+       extern void dummy (int [sizeof (struct {...})]);
+       extern int (*dummy (void)) [sizeof (struct {...})];
+
+     can be repeated.
+
+   * Should the implementation use a named struct or an unnamed struct?
+     Which of the following alternatives can be used?
+
+       extern int dummy [sizeof (struct {...})];
+       extern int dummy [sizeof (struct verify_type__ {...})];
+       extern void dummy (int [sizeof (struct {...})]);
+       extern void dummy (int [sizeof (struct verify_type__ {...})]);
+       extern int (*dummy (void)) [sizeof (struct {...})];
+       extern int (*dummy (void)) [sizeof (struct verify_type__ {...})];
+
+     In the second and sixth case, the struct type is exported to the
+     outer scope; two such declarations therefore collide.  GCC warns
+     about the first, third, and fourth cases.  So the only remaining
+     possibility is the fifth case:
+
+       extern int (*dummy (void)) [sizeof (struct {...})];
+
+   * This implementation exploits the fact that GCC does not warn about
+     the last declaration mentioned above.  If a future version of GCC
+     introduces a warning for this, the problem could be worked around
+     by using code specialized to GCC, e.g.,:
+
+       #if 4 <= __GNUC__
+       # define verify(R) \
+          extern int (* verify_function__ (void)) \
+                     [__builtin_constant_p (R) && (R) ? 1 : -1]
+       #endif
+
+   * In C++, any struct definition inside sizeof is invalid.
+     Use a template type to work around the problem.  */

+   Return 1.  */
