The dll and static library port was developed and tested under Microsoft
Visual C++ 6.0.  The former support for the Borland C++ compilers has been
discontinued; bcc-compiled DLLs are not universally usable because of their
requirements for special Borland runtime libs (and probably some calling
convention specialities).
Compilation for 16-bit Windows 3.x is no longer supported.
