Subject: generator.ml: avoid a warning about signed overflow in tests.c
X-Git-Tag: 1.0.69~22
X-Git-Url: http://git.annexia.org/?p=libguestfs.git;a=commitdiff_plain;h=de81a7d930a6a2ad558eff9396da20237e06ccc1;ds=sidebyside

generator.ml: avoid a warning about signed overflow in tests.c

* src/generator.ml: Emit "unsigned long int n_failed;" rather than
"int failed;", to avoid warning from gcc about "assuming signed
overflow does not occur when simplifying conditional to constant".
