Lyle Johnson's interface to Borland C++, with a few editorial comments by me.
Two major points:
* lots of overlap with MSVCCompiler; the common code really should be
factored out into a base class, say WindowsCCompiler
* it doesn't work: weird problem spawning the linker (see comment for
details)

+# This implementation by Lyle Johnson, based on the original msvccompiler.py
+# module and using the directions originally published by Gordon Williams.
+
+# XXX looks like there's a LOT of overlap between these two classes:
+# someone should sit down and factor out the common code as
+# WindowsCCompiler! --GPW
+
+# XXX Lyle reports that this doesn't quite work yet:
+# """...but this is what I've got so far. The compile step works fine but
+# when it runs the link step I get an "out of memory" failure. Since
+# spawn() echoes the command it's trying to spawn, I can type the link line
+# verbatim at the DOS prompt and it links the Windows DLL correctly -- so
+# the syntax is correct. There's just some weird interaction going on when
+# it tries to "spawn" the link process from within the setup.py script. I'm
+# not really sure how to debug this one right off-hand; obviously there's
+# nothing wrong with the "spawn()" function since it's working properly for
+# the compile stage."""
