#### Start of system configuration section. ####
# Note that this configuration takes place not when gcc/g77 are
# configured; rather, when g77 is built, it configures this
# runtime stuff.  That means configuration happens for each
# stage of a bootstrap build, for example.

# $(srcdir) must be set to the g77 runtime source directory
# (g77/f/runtime/).
