Hmph, so the idea is to have
/* do not include git-compat-util.h here */
int wrapped_fileno(FILE *f)
{
return fileno(f);
}
in compat/fileno.c and then do something like this
#ifdef fileno
#undef fileno
#define fileno(x) wrapped_fileno(x)
#endif
for FreeBSD in git-compat-util.h or something like that?
I think I can buy that.
