# XXX This is a hack, but it seems to work.  libgcc1.a is supposed to be
# compiled by the native compiler, and libgcc2.a is meant to be compiled
# by *this* version of gcc.
#
# Normally, this does not make any difference, since we only have gcc, but
# when bootstrapping from gcc-2.6.3, we have to use the freshly built 2.7.2
# compiler for some of the libgcc2.c __attribute__ stuff.
#
# We now depend on a bootstrap pass (normally in `make world') to build
# and install the new version of gcc before we get here.  This makes
# finding the new version (XCC) easy but may break finding the old version
# (CC).
