 *  DLL symbol extraction based on file format from alib (anthonyw.cjb.net).
 *  Option processing shamelessly cadged from winebuild.
 *  All the cool functionality (prototyping, call tracing, forwarding)
 *  relies on Patrik Stridvall's 'function_grep.pl' script to work.
 *  http://www.kegel.com/mangle.html
 *  Gives information on the name mangling scheme used by MS compilers,
 *  used as the starting point for the code here. Contains a few
 *  mistakes and some incorrect assumptions, but the lists of types
 *  are pure gold.
