You're right that is a problem. See, C++Builder only does Win32 apps, and
getting Win32 apps to communicate with a 16 bit DLL is painful, ugly, and
non-portable even between Win9x and WinNT. There are two methods of
"thunking" and one works on WinNT and one works on Win95. It ain't very
fun.

For more info, search for thunking on http://msdn.microsoft.com. Also,
there's a *very* simplistic component on Torry's site that might help for
*real simple* cases:
