32 bit mode graphics in DOS

I recently acquired Borland C++ 4.5 and was going to try out Ground up Graphics graphics library but I can't get it to compile right.  If I compile to DOS code, it gives an error saying "32 bit mode instruction detected", if I change the compile options to "allow 32 bit mode", it seems to get further but says it can't find math287.h.. or similar.  I can't find a header file anywhere by this sort of name.  Do I need to get Borland's PowerPack for DOS or is there something simple that escapes me?  287 is probably significant as a Math coprocessor which may have something to with float math being enabled?  Suggestions please...

If you use graphics Lib. you can only compile it as DOS 16bit
program, so check compiler and linker settings.

If you specify 32bit mode, then you have to compiler as console
application. You can not use Borland graphics lib. Besides that
BC4.5 had some problem to successfuly generate 32 bit application.  

good luck
