I have applied the 3 parts of your series that were good, and fixed the
remaining problems. Indeed, the problems with the overload conflicts
(in cl_combine, fprintdecimal, fprinthexadecimal) that are caused by the
fact that intptr_t may be 'int', may be 'long', may be 'long long', were
hardest to resolve. I chose not to introduce platform-dependent #ifs
(too hairy to maintain), nor an autoconf test (because the include files
are supposed to be usable by different compilers, and different compilers
may define intptr_t differently), but instead use an inline function
redirection.
