I am not say it is hard. But I find having a .c/.h pair more useful and easier to work with.

No lol

Because looking up a macro name for each library is easier than adding a c file to your makefile? You could still always do

  #include "impl.c"

and this would still be nicer than

  #define XZUGG_IMPL
  #include "impl.h"
