  22  *
  23  *  Option processing shamelessly cadged from winebuild.
  24  *
  25  *  All the cool functionality (prototyping, call tracing, forwarding)
  26  *  relies on Patrik Stridvall's 'function_grep.pl' script to work.

  28  *  http://www.kegel.com/mangle.html
  29  *  Gives information on the name mangling scheme used by MS compilers,
  30  *  used as the starting point for the code here. Contains a few
  31  *  mistakes and some incorrect assumptions, but the lists of types
  32  *  are pure gold.
