questions about qsort, t_size, /usr/include/iso/stdlib_iso.h and warning: argument #4 is incompatible with prototype:

libtool,

I have a quick question for you and I am hoping you can help or point me
in the right direction.

I am running Solaris 8 SunOS 5.8 and I am getting the following message
when I compile a program:

line 207: warning: argument #4 is incompatible with prototype:
        prototype: pointer to function(pointer to const void, pointer to
const v
oid) returning int : "/usr/include/iso/stdlib_iso.h", line 109

I am getting the same error in three places, but line 207 in the program
is:

   qsort( linkfiles, cnt, (size_t) Len, lfcomp );

The line 109 in stdlib_iso.h is:

   extern void qsort(void *, size_t, size_t, 
      int (*)(const void *, const void *));
   
Any ideas what could be causing this?  They are just warnings, but I
think they are impacting the results of the program.

If you have any idea what this could be or you have any suggestions
please let me know.

Thanks,
Rodney
