I was having problems creating a DLL in Borland C++ v3.1.
I plannned on calling this DLL from VB 4.0
I had identical two copies of the source code.
When compiled....one would work, the other would not.
I finally discovered that the copy with a .CPP extension (the default)
was causing the compiler to link in some C++ modules that would
prevent the DLL from working. The version with a .C extension
worked fine.

Just a note to anyone who might experience the same problem.

Thanks to all of you who wrote to me with advice.
