If I got the function pointer syntax right then something like this would be a workaround maybe? 

void (perls_free)( void*p ) = &free;
#undef free

// free() should now refer to the crt free() and use perls_free() for 
+XS

Though the long term solution would be to remove the #define from the header file in favour of Safefree().

That said, the whole area of memory allocation functions and macro's in the Perl codebase is a mess. Sometime last year I did a not totally crude grep and eliminate duplicates process on the sources and discovered that between the 4 basic functions--malloc(), calloc(), realloc() & free()--there were (from memory) 114 different ways of calling them through the multiplicitous variations of functions and macros. It's truely amazing that there are many more memory problems than there are.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
