Well I put in gcc2952s.zip a script for building DJGPP
targetted cross-compiler (in directory gnu/gcc-2.952/build.cross).
I have tested it on Linux only (Slackware-7.0). 

Other way:
I put binaries of 
	binutils 14 March CVS version (slightly newer as bnu2951s.zip)
	cross-compiler binaries 
at  
	http://www.lanet.lv/~pavenis/djgpp

Binaries are built on Slackware-7.0 but they should work also on
RedHat-6.1.

Installation of Slackware package:
	unpack .tgz archive in root directory (cd \; tar xvf ....)
	run script /install/doinst.sh)
