# There are two distfiles that may or may not be needed, depending on
# what is already installed on the system.  First, we need an executable
# for the Modula-3 compiler, in order to compile the new compiler, which
# is written in Modula-3.  Often, there will already be such an executable
# installed on the system.  Second, we need many files from gcc-2.7.2.1.
# Often, we can find these in the system sources, under "/usr/src/contrib".
#
# This code tries to avoid fetching the distfiles, unless necessary.
# We look on the system to see whether the necessary files are present,
# and use those if we can.  If we cannot find the needed files, we
# fetch the distfiles.

# For the Modula-3 compiler, we look in ${PREFIX} and in /usr/local.
