21 * DLL symbol extraction based on file format from alib (anthonyw.cjb.net).
23 * Option processing shamelessly cadged from winebuild.
25 * All the cool functionality (prototyping, call tracing, forwarding)
26 * relies on Patrik Stridvall's 'function_grep.pl' script to work.
28 * http://msdn.microsoft.com/library/periodic/period96/msj/S330.htm
29 * This article provides both a description and freely downloadable
30 * implementation, in source code form, of how to extract symbols
31 * from Win32 PE executables/DLLs.
33 * http://www.kegel.com/mangle.html
34 * Gives information on the name mangling scheme used by MS compilers,
35 * used as the starting point for the code here. Contains a few
36 * mistakes and some incorrect assumptions, but the lists of types
