Subject: Non-present 80387 when assembling



I am trying to use the gnu C compiler on a number of DOS PCs.  The
compiler was built for me from by a colleague who tells me that it was
djgpp version 1.11.

I am experiencing problems when assembling some of the files compiled
by gcc as I get the following error.  I am using gcc version 2.5.8 and
GNU assembler version 2.1 (m68k-unknown-coff).

Is there a limitation on what hardware is required to use the
assembler or do I just need to re-link it with a math library?  Is
there a math library somewhere which will use an 80387 if there is
one in the machine being used?

I am also interested in finding out what the RAM and disk requirements
are for djgpp.

Would a more recent version of djgpp help me with my math library
problem and would it run in smaller hardware in general?



Thanks for the help,
