There is a way to clean it up a teensy bit.
Tuck all the random ifdef crud in one macro and then have cgen use
that macro.

something like

#if defined (__STDC__) || blah ...
#define CGEN_HAVE_STRINGIZE 1
#else
#define CGEN_HAVE_STRINGIZE 0
#endif

You might even throw that in include/opcodes/cgen.h.
