I think you are missing a "*": 

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

But that still risks the second half of my warning:

(but don't use "free" any further down in your code, even indirectly via some other obscure C-preprocessor macro).

which seems rather difficult to avoid with any certainty given your assessment of the current messiness. :)

Update: BTW, I am aware that the "&" is "optional", but I consider this simply to be a mistake on the part of the ANSI C definers. (:
