# To change the values of `make' variables: instead of editing Makefiles,
# (1) if the variable is set in `config.status', edit `config.status'
#     (which will cause the Makefiles to be regenerated when you run `make');
# (2) otherwise, pass the desired values on the `make' command line.

#To do:
#use $(srcdir) to make compilation in a non-srcdir possible

#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."
