I appreciate that you came back to tell me that what I
said was correct.  I almost always hear if what I suggested
didn't handle a problem, but when I post a winner I rarely
hear back! <g>

Nah.  He obviously doesn't know to make DLL exports
__stdcall as is the custom in Windows programs.  Since he
doesn't know (or doesn't care), why bother?  Just fix it
yourself.

Make a module definition file for the DLL.

  impdef  DllName.DEF  DllName.DLL

Pull it up in an editor and you'll see a section something
like this:

EXPORTS
   HaltAndCatchFire  @1
   JumpOffBridge  @2

And add lines with aliases to the end of it like this:
   _HaltAndCatchFire  = HaltAndCatchFire
   _JumpOffBridge  = JumpOffBridge

Then make an import library for it like this:

  implib -c DllName.LIB DllName.DEF

When you add the import library to your project it will then
supply underscored symbols for all the items for which you
have provided an alias.
