# Since the 'compare' process will fail (on debugging information) if any

# the build directories constant as well. For the latter, we use naked names
# like 'gcc', because the scripts in that directory assume it.  We use
# mv on platforms where symlinks to directories do not work or are not
# reliable.

# At the end of the bootstrap, a symlink to 'stage3-gcc' named 'gcc' must
# be kept, so that libraries can find it.  Ick!

# It would be best to preinstall gcc into a staging area (and in the
# future, gather there all prebootstrap packages).  This would allow
# assemblers and linkers can be bootstrapped as well as the compiler
# (both in a combined tree, or separately).  This however requires some
# change to the gcc driver, again in order to avoid comparison failures.
