A while ago, with some help from Andrew Crabtree, I managed
to compile egcs and pgcc (including g77) for DJGPP. Recently,
somebody asked me for those instructions. Well, here they
are. I did it in a very convoluted way, by building a cross-
compiler under Linux, and then using the cross-compiler to make
the DOS executables. I have two shell scripts: the first which
makes the cross-compiler, and the second which makes the DOS-native
compiler. They are tacked onto the end of this post.
I would be happy to provide .ZIP files of egcs or pgcc (C, C++, G77)
compilers for DJGPP, if somebody can tell me how to contribute them.

# Make gcc-dos (a cross-compiler for MS-DOS running under Linux)
#
# Version 1.0 4/17/1998 Scott Blackman <scott DOT blackman AT vanderbilt DOT edu>
#
# Requirements:
# You need to have a working C compiler (preferably the same version
# as the cross-compiler, i.e. egcs- or pgcc-${EGCS_VER})
# This script needs write permissions to $PREFIX
#
# Credits:
# The overall plan is based on the DJGPP FAQ answer 22.7 about building
# a cross-compiler.
# http://www.delorie.com/djgpp/v2faq/faq168.html#Cross-DJGPP
#
# For compiling pgcc, I incorporated information from Andrew Crabtree's
# binary distribution of pgcc for DJGPP. See his readme for other
# useful information.
# http://www.goof.com/pcg/binaries-djgpp.html
# or <andrewc AT rosemail DOT rose DOT hp DOT com>
#
# PGCC NOTE: When peep-spills is enabled (starting at -O3), the fortran
# f/intrin.o compiles incorrectly, causing the MS-DOS native
# f771 to segfault. So I routinely disable this optimization.
