/*
  This program is a tool to build .def file
 used by lib.exe to build the DLL on Windows.
  It takes the output of a "dumpbin" over an
 archive library and produces the .def file for
 this library. For example :
   DOS> dumpbin /out:tmp /symbols MyLib.arc
   DOS> win32def.exe MyLib < tmp > MyLib.def
 Note that win32def is a standalone program that 
 can be easily reconstructed with :
   DOS> cl /Fowin32def.exe win32def.c
