# makefile to compile MCPP version 2.7.2 and later for CygWIN / 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 do:

#       make

#       make install

# To make GCC-specific-build of MCPP:

#       make COMPILER=GNUC

#       make COMPILER=GNUC install

# To re-compile MCPP using GCC-specific-build of MCPP do:

#       make COMPILER=GNUC PREPROCESSED=1

#       make COMPILER=GNUC PREPROCESSED=1 install

# To make libmcpp (subroutine build of mcpp):

#       make MCPP_LIB=1 mcpplib

#       make MCPP_LIB=1 mcpplib_install

# To make testmain using libmcpp (add 'DLL_IMPORT=1' to link against DLL):

#       make [OUT2MEM=1] testmain

#       make [OUT2MEM=1] testmain_install
