Did you do ./configure --solo?

What is the non-ANSI compliant declaration you are seeing?  On what compiler with what message?  According to the C99 standard, ptrdiff_t is defined in stddef.h.  So if stddef.h is not #included (and for Z_SOLO, nothing is #included), then you could define ptrdiff_t to be whatever you like.
