The new C language standard in development, C9X, specifies complex data
types, a complex.h header, and a standard function library.  GCC can
do the complex types.  An implementation of the header and function library
for GCC can be obtained from this location --
  ftp://ftp.std.com/pub/astronomy/cephes/c9x-complex.zip

The function names, by the way, are not overloaded as they would be
in C++.  You write "clogf" for example, meaning float precision complex log.
