Hi,
in gcc 4.1, the following sample throws a warning:
/* gcc-4.1 -c test.c -Wall -Wconversion */
#include <stdbool.h>
static int a(bool b)
{
return b ? 1 : 0;
}
int main(void)
{
return a(true);
}
test.c:10: warning: passing argument 1 of âaâ with different width due
to prototype
In gcc-4.3 however, that warning is gone. Where could I read more about
this change?
