# IMPORTANT NOTE: in order to compile GCC 4.8, you need the GMP, MPFR and MPC development libraries.
# For example, if you have installed them yourself in $PREFIX, you'll have to add --with-gmp=$PREFIX --with-mpfr=$PREFIX --with-mpc=$PREFIX.

# NOTE: the second rm -rf is commented, because it's not strictly necessary.
