# makefile to compile MCPP version 2.7.2 for Linux / GCC / GNU make
#       2008/09 kmatsui
#
# First, you must edit GCCDIR, BINDIR, INCDIR, gcc_maj_ver and gcc_min_ver.
# To make compiler-independent-build of MCPP:
#       make
#       sudo make install
# To make GCC-specific-build of MCPP:
#       make COMPILER=GNUC
#       sudo make COMPILER=GNUC install
# To re-compile MCPP using GCC-specific-build of MCPP do:
#       make COMPILER=GNUC PREPROCESSED=1
#       sudo make COMPILER=GNUC PREPROCESSED=1 install
# To link malloc() package of kmatsui do:
#       make [COMPILER=GNUC] [PREPROCESSED=1] MALLOC=KMMALLOC
#       sudo make [COMPILER=GNUC] [PREPROCESSED=1] MALLOC=KMMALLOC install
# To make libmcpp (subroutine build of mcpp) and mcpp binary linking it:
#       make MCPP_LIB=1 mcpplib
#    	sudo make MCPP_LIB=1 mcpplib_install
# To make testmain using libmcpp:
#       make [OUT2MEM=1] testmain
#       sudo make [OUT2MEM=1] testmain_install

#   Specify whether make a compiler-independent-build or GCC-specific-build
