As well as a compiler what you need is a linker/locator for producing
ROMable code from your compilers output.  You would then chose a
compiler which is supported by the linker locator.  Although this is
not the only one available I am currently using Csi-Locate from
Concurrent Sciences with the Watcom C++ compiler to produced an
embedded 32 bit protected mode application.  The Watcom compiler is
the standard PC product and you can debug the code on a PC (depending
on the architecture of the embedded system).  Concurrent Sciences also
produce a remote debugger for downloading and debugging the code
directly on your embedded system hardware.  Contact details for
Concurrent Sciences are (US phone numbers):
