Re: building gcc-2.95 for linux -> m68k-elf

["Charles Gauthier" <Charles.Gauthier@iit.nrc.ca>]

Try this:

cd gcc-2.95
ln -s ../newlib-1.8.1/newlib newlib

Then add the --with-newlib flag when you configure. The build process will detect the existence of newlib, and copy the required header files into the build directory, and then use them. There is no need to pre-install the files. They will get
installed when you install gcc (newlib gets installed with it).
