I cannot compile the following program:

--- BEGIN sl.C
#include <string.h>

int main(void)
{
  int q = strlen("foo");

  printf("%d\n", q);
}
--- END sl.C

After preprocessing on my machine with 

	g++-2.4 -v -E sl.C > sl.i >[2] ppo

the preprocessor standard error output is:

Here's the verbose output from g++ when I try to compile it with 
	g++-2.4 -v sl.i -c >[2] co

And no sl.o file is produced.  My problem is with

	/usr/local/lib/g++-include/string.h:28: declaration of `int  strlen (const char *)'
	<built-in>:0: conflicts with built-in declaration `long unsigned int  strlen (const char *)'

.  There's a comment in /usr/local/lib/g++-include/string.h that says:

	// NOTE: If you get a error message from g++ that this declaration
	// conflicts with a <built-in> declaration of strlen(), that usually
	// indicates that __SIZE_TYPE__ is incorrectly defined by gcc.
	// Fix or add SIZE_TYPE in the appropriate file in gcc/config/*.h.
	size_t    strlen(const char*);

size_t is #defined to be `_G_size_t', and _G_size_t' is typedeffed to
`int'.  As nearly as I can tell, the type of `strlen' is hard-wired in
g++ to be `unsigned long int'.  So the only option seems to be to change
the definition of _G_size_t to be `unsigned long int'.

However, I've looked at the source for our strlen and it really does
return `int', not `unsigned long int'.  This is probably a deficiency in
our environment, but we'd prefer not to have to replace stlen.  Our
vendor-supplied headers define size_t to be `int' and I'm reluctant to
mess with this.

I'm not sure how to proceed with this.  In the meantime we can't use
g++-2.4 because of these type conflicts.  g++ 2.3.3 is working fine for
us; I'm not sure what is really different.

What do you advise?
