I think something like:

#ifndef FC_NAMELANG
#define FC_NAMELANG "namelang"
#endif
#ifndef FC_PRGNAME
#define FC_PRGNAME "prgname"
#endif

put after fontconfig's "MAKE_FUNCPTR"s would be the cleanest way.

But yes, what happens when run with an old version of the library;
does FcPatternAddString() return an error or it is ignored, and does
that make the resulting font useful or not?

Huw.
