* Specmaker - A Wine DLL tool
*
* Copyright 2000 Jon Griffiths
*
* References:
* DLL symbol extraction based on file format from alib (anthonyw.cjb.net).
*
* Option processing shamelessly cadged from winebuild (www.winehq.com).
*
* All the cool functionality (prototyping, call tracing, forwarding)
* relies on Patrik Stridvall's 'function_grep.pl' script to work.
*
* http://msdn.microsoft.com/library/periodic/period96/msj/S330.htm
* This article provides both a description and freely downloadble
* implementation, in source code form, of how to extract symbols
* from Win32 PE executables/DLL's.
*
* 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.
