  OK let clear some misunderstanding:

try this:

vi test.c
#include <stdio.h>
typedef float size_t;
main()
{
   size_t a = strlen("You missed");
   int    b = strlen("You missed");
   short  c = strlen("You missed");

   printf("You missed %f %d %d %d\n", a, (unsigned long)a, b, c);
}

and cc test.c, gcc test.c

what you get is: NO complain at all. compiler doesn't care whether
size_t is a long, float or anything, as long as there is no
prototyping. 

  In
/usr/dist/gnu/lib/gcc-lib/sparc-sun-sunos4.1.3/2.4.5/include/string.h,
it prototype strlen as size_t, and if you have that include and have
int a = strlen(...) then you will have problem. If the header files
you have are not the gcc 2.4.5, you have a different typedef. Also,
there was a inconsistant using of size_t in libg++ which has been
fixed. I have install gcc-2.4.5, libg++-2.4 and IV 3.1 on
sparc-sun-sunos4.1.3 and I don't have to modified SIZE_TYPE (as what
the src said "In 2.4 it should work to delete it". Anyway, you must
have done something wrong.

  Also, gcc's notation should be right, strlen should be unsigned int,
what would it mean by a minus string lenght?
