# This Makefile is intended only for DJGPP use.
# It is mainly a copy of the main Makefile, but tends to get out of sync
# with it.  A merge would probably be appropriate.

# Primary targets:
# gc.a - builds basic library
# libgc.a - builds library for use with g++ "-fgc-keyword" extension
#	    -fgc-keyword was never really available.  Historical
#	    interest only.
# c++ - adds C++ interface to library
# cords - adds cords (heavyweight strings) to library
# test - prints porting information, then builds basic version of gc.a,
#      	 and runs some tests of collector and cords.  Does not add cords or
#	 c++ interface to gc.a
# cord/de$(EXE_SUFFIX) - builds dumb editor based on cords.
