Building C++ library DLL

	I'm not sure if this happens for C++, because this only happened
	for me, but I found that if things were exported more than once
	from the library, the extra compiler directives for DLL's caused
	the CD compiler (gcc 2.90?) to barf, so you might check to see
	you're class isn't getting exported more than once.
