Borland uses a different .lib format than microsoft, and
borland by default adds underscores to all 'cdecl' symbols.
The compiler has an option to turn them off, but then the runtime
libraries have to be rebuilt or nothing will link.
There are other ways to deal with the underscores:
IMPLIB is the borland tool to make a borland .lib from a .dll so you
can statically link to it. The new implib has a '-a' option to add
the underscores that borland expects, so stuff matches when linking
to a non-borland dll.
When linking your dll, a .def file is required to change the names
published by the dll, to do the opposite and get rid of the underscores.
The EXPORTS section allows you to set AliasName=InternalName for
each published entry point.
This didn't work correctly in borland 5.0 - hopefully it's been
fixed in 5.5
In other words, I haven't tried it, but that's what to look out for.
