Gcc 2.5.8 source code is available from any gnu ftp sites, like
anonymous@prep.ai.mit.edu:pub/gnu/gcc-2.5.8.tar.gz and
anonymous@ftp.uu.net:packages/gnu/gcc-2.5.8.tar.gz. It compiles right
out of box. Just unpack the source code and do 

	configure [i386-linux|i486-linux] --prefix=/usr --local-prefix=/usr/local

You should follow the instructions in INSTALL. You may have to add -I./include
to CFLAGS in the stage 2 or above.
