Yes we do the same, under BSD/386 rather than Linux.  In fact any Unix
system that can run gcc can (fairly) easily be configured to build a
cross-compiler using --target=i386-go32.  Linux is a red herring:
there all sorts of different Unix systems (e.g. FreeBSD) with
different native object code formats, why should we choose to be
"compatible" with Linux only?

And when Windoze95/Chicago eventually arrives, how much longer will
vanilla MSDOS survive: Chicago runs 32-bit NT/COFF executables too.
Although I think that ELF is a much more elegant format (we use it
ourselves for our tools), it looks like compilers whose primary
emphasis is DOS (and therefore soon Chicago) should standardise on
NT-compatible COFF.  It is a golden opportunity that Microsoft picked
an object code format which is easily supported by the GNU tools.

Products like Toolbuster use GCC to provide a Unix compiler and
run-time environment for NT/Chicago, but you have to pay for them.  It
would be great if DJGPP could form the basis of a free alternative.
