#from the gcc Makefile: 
#"Deletion of files made during compilation.
# There are four levels of this:
#   `mostlyclean', `clean', `distclean' and `realclean'.
# `mostlyclean' is useful while working on a particular type of machine.
# It deletes most, but not all, of the files made by compilation.
# It does not delete libgcc.a or its parts, so it won't have to be recompiled.
# `clean' deletes everything made by running `make all'.
# `distclean' also deletes the files made by config.
# `realclean' also deletes everything that could be regenerated automatically."
