#
# ** MANUAL BUILDS **
#
# Use: 
#	setenv RC_ARCHS='i386 m68k ...'
#	setenv RC_CFLAGS='-arch i386 -arch m68k ...'
#	make debug TARGETS='i386 m68k ...' HOSTS='i386 ...'
#
# from this directory to do manual builds.  The build compiler(s) will
# appear in ./obj/cc-<target>-on-<host>/ subdirectories of here.  Use
# "./xgcc -B./" in there to run the specific compiler.  You can also
# just cd to a specific ./obj subdirectory and type "make <foo>" to build
# a specific program, like "cpp" or "cc1objplus".  

#
# ** AUTOMATIC BUILDS **
#
# Automatic builds strictly follow the RC makefile API standards.
#

# Enable NeXT extensions to (gnu)make.

# DO_SYMLINKS set to 'yes' will all the full gcc2 installation which
# includes generating sym links in various places.  These sym links
# are in the same places with the same names as those generated by
# gcc3.  We may not want to clobber gcc3's sym links.  Thus setting

# COEXIST_WITH_GCC3, when set to non-null modifies the original gcc2
# installation in the following ways:
#
#  1. libcc.a is installed in /usr/lib/gcc/darwin/default instead
#     of /usr/lib and a sym link is placed in /usr/lib to the new
#     location.
#
#  2. libcc_noc++.a is installed in /usr/lib/gcc/darwin/default instead
#     of /usr/local/lib and a sym link is placed in /usr/local/lib
#     to its new location.
#
#  3. /usr/bin/cc, /usr/bin/c++, and /usr/bin/c++filt become sym links
#     to /usr/bin/gcc2, /usr/bin/g++2, and /usr/bin/c++filt2 respectively.
#
#  4. A /usr/bin/gcc and /usr/bin/cc are installed as a sym links to
#     /usr/bin/gcc2.
#
#  5. A /usr/bin/g++ and /usr/bin/c++ are installed as sym links to
#     /usr/bin/g++2.
#
# By making the sym links instead of having the actual files in 
# those locations makes it easier to coexist with gcc3 (hence the
# name for the switch) and also makes it easier to switch between the
# two compilers.
