# bsd.gcc.df.mk  - Reaction to USE_GCC on DragonFly
#
# The primary base compiler is used is possible, otherwise the ports default
# is used unless there's a hard specification.
#
# For DragonFly 4.1+, the primary base compiler is gcc50 and for earlier
# releases, the primary base compiler is gcc47.  The avoidance of the use of
# the alternate compiler is intentional.
