I am successfully using egcs-1.1 with root. What you have to do is
recompile root as described on the download page, i.e. download the RH5.1
binary version of root and the root SDK, cd to the src directory, link
Makefile.linuxegcs to Makefile, then make; make install.
No problems after that (except with the games demo).
Good luck,
Matt
