Use parenthesis for "#if defined foo" -> "#if defined(foo)" - portability.
Use ANSI C comments in flstring.h, which is included from both C++ and
C code.
Move prototypes for OSX inside existing "C" wrapper in flstring.h.
Simplify M_PI and M_SQRT2 definitions in FL/math.h; no need to define
them twice...
