  Actually, I think that's incorrect.
  Everyone has some *familiarity* with the C preprocessor, which surely is
  an advantage. And maybe most C programmers think they they understand
  it. But in my experience, very few understand the fine details of cpp
  macro expansion.
  E.g., you probably wrote those GLUE and GLU1 macros without any
  difficulty, but understanding how that works and why really makes you a
  Great Guru to the vast majority of C programmers.
Ehum, I don't understand with which cpp quirk that indirection is
coping...  I.e., I'd expect __GMP_GLU1 and __GMP_GLUE to do the exact
same thing.  Darn, and I am an ex compiler hacker.

Perhaps we should use m4 for preprocessing C instead?  :-)
