DOS cross-development under SCO Unix?

[Rich Braun]

My company does much of its C source code development under DOS, and is
currently switching over to a DOS extender product to break the 640K
barrier.

Recently I started to play with the DOS cross-development support provided
by SCO, and I must say I'm pleasantly surprised at how easy it is to set
up and at how much faster the compiler and linker run under Unix than
under DOS.  (Microsoft C running in 386 native mode, producing code for
an 8086, compiles a whole lot faster than it does in 8086 mode.)

Now the question I have for SCO and third-party vendors is this:  is there
any way to cross-develop under Unix for an extended DOS target
environment?

This is not a particularly urgent need for us, but it's oh-so-much-nicer
to use the Unix development environment than the DOS environment,
particularly considering the speedup of the 'make' process.  And given
our shift to DOS extenders, we cannot make much use of the SCO cross-
development environment as it stands today.
