> * The FD_ZERO() macro produces the following statement:

In my previous mail 'PROPOSED FIX to remove warning in 1.1.5-3 sys/types.h'
I found exactly the same warning and propose a solution. Maybe -ansi or
even -pedantic will raise that warning.
Here is a copy of my previous mail.
--- copy ---
# define FD_ZERO(p) (__extension__ (void)({ \
int i; \
char *__tmp = (char *)p; \
for (i = 0; i < sizeof (*(p)); ++i) \
*__tmp++ = 0; \
}))
raise a new warning 'signed unsigned comparison'
I suggest to replace
int i;
with unsigned int i;
A better solution should be to include stddef (for size_t) and have:
size_t i;
which is the type returned by sizeof.
But, unless I'm totaly wrong, the fastest solution is to use memset that
will be expanded inline with assembly code. Right?
