Package: autoconf
Version: 2.59a-8
Severity: normal
Hi,
With my current gcc (4.0.2-10), the following code:
int main() { return 0; }
Will warn: function declaration isn't a prototype
if compiled with -Wstrict-prototypes.
Since that is the signature for main which autoconf wraps its tests in
when creating conftest.c -- then tests which should normally succeed,
will fail if the language is C, and CPPFLAGS include -Wstrict-prototypes,
and -Werror (the latter being my preferred habit for release builds).
Hopefully this is as simple to fix as writing out one of the standard
prototypes for the main function. If main(void) is no good for some
reason, then main(int a,char **b) { (void)a; (void)b; } is a bit uglier
to look at, but provides the right amount of realism for this to succeed
in more cases where it should.
Turning off useful compile time flags (that will actually be used at
compile time) to make all the right tests succeed doesnt seem quite
like the right answer otherwise..
cheers,
Ron
