Configure is a big pain. Yes, I suggest to use strictly ansi C, then we are fine. If we need any other math libraries besides what's in the ansi C, then I suggest we simply attach the C file implementing for example the bessel functions or somethig -- or, we just use mpfr/gmp, but then you are right that we need some configure script -- I have a good experience with cmake.
