A short version that produces it:

int funcc(void) { return 0; }
#define strlexx strlen
extern int strlen(const char *a);
extern int strlem(const char *a);
extern int strleo(const char *a);
char buffer[20];
int main(void)
{
 for(;;)   if (funcc())   if (strlexx(buffer))   if (funcc()) ;
}

Interrestingly enough it manages to distinguish between strlen and
strlem/strleo with the name strlen changed in all libraries. Even without
libraries (a binary search of the tree says that strlen doesn't occur
anywhere except the help documentation and the exe files - windows version)
it manages to behave differently.

In short, it seems that if I name strlen something other than strlen, and
then rebuild the libraries, it works?
