//  Definitions for complex number support.  The ANSI C++ proposal 
//  specifies a templated class for this, e.g. complex<double> or 
//  complex<float>, but not all compilers currently support this.  TNT
//  provides a mechanism to accomodate any complex number class,
//  using "DComplex" and "FComplex" names for double-precision
//  and single-precision instances, respectively.  For example,
//  if your system uses the older "Complex" number class, compile as
//
//   CC -DTNT_DCOMPLEX_TYPE='Complex' 
//  
//  Now DComplex
