Ampro Little Board 700 and DOS/Linux/Windows 2000

What Integrated Development Enironment () could I use for an Ampro
embedded PC that has both DOS on one partion and Timesys Linux on the
other? The Borland C++ Builder running on my desktop for development
would not work because Builder 6.0 will not generate 16 bit console
applicationes like 5.5 did.

Should I put Windows 2000 on my embedded PC? I am just using the
embedded PC for proof-of-concept with porting eventualy to a smaller
target system using probably the PowerPC, and have not determined the
OS.

Should I buy Botland's Turbo C++ Suite ($69.95)?

There are many other choices too, but I don't want to buy anything
else.

What about the Timesys Linux that came with the Ampro Little Board
700? Is there there a free IDE or command line compiler for that? And
I heard that Linux may cost soemthing soon due to a law suite. Maybe I
should stay away from Linux?
