# -----------------------------------------------------------------------------
# Bootstrapping
# The stage1/stage2/stage3 business is quite delicate. Here's how it works:
#
# - the variable $(stage) holds the current stage number. To build a
# particular stage, you say 'make stage=N' where N is 1, 2, or 3.
# N defaults to 1.
#
# - for stage N, object files and .hi files are placed inside
# the directory stageN, in subdirectories as per the sources.
#
# - .hi-boot files are *linked* into the stageN tree, because in GHC 5.05+
# the .hi-boot file must reside in the same place as the .hi file.
#
# - we use explicit -o and -ohi options to direct the output from C &
# Haskell compilations.
#
# - we generate a different .depend file for each build. They need to be
# different, because each stage might include different files: stage1
# might not include GHCi, for example. For each stage, a normal .depend
# file is generated, and then post-processed to add the correct stageN/
# prefix to each object and .hi filename. The resulting .depend file
# is named .depend-$(stage). See the end of this Makefile for details.
#
# - normal implicit rules don't work any more, because they're of the form
#
# %.o : %.hs
#
# whereas we really need
#
# stageN/%.o : %.hs
#
# so suffix.mk now defines the appropriate suffix rules when
# $(odir) is set to a non-empty value. Here we set $(odir) to
# stage1, stage2, or stage3.
#
# There are other plausible designs that might work, but each has different
# problems:
#
# - using -odir and -hidir: GHC <= 4.08 doesn't support -hidir, and
# anyway -odir puts all the objects in one directory (strips off the
# subdirectory part), which eventually forces us to use VPATH to find
# the sources. I have a really bad feeling about VPATH.
#
# - invoke make in the stageN subdirectory. This probably requires VPATH
# too.
#
# - create a link tree. The problem with requiring link trees is that
# Windows doesn't support symbolic links.

# I'm exec'ing $(SCRIPT_SHELL), rather than the usual #!/bin/sh, to make
# sure that the right shell is invoked. If we use /bin/sh, then
# when ghc-inplace is invoked from a Cygwin Python (which is the only Python
# that seems to run the test-suite correctly), we get the Cygwin shell,
# and it in turn interprets the path-names in the second (exec) line
# differently to the MSys shell. That's bad, because ghc-inplace must
# also work when invoked from MSys shells
#
# To figure out what the MSys shell is, we cd to '/bin' and do 'pwd -W'
# On MSys, the -W flag prints out the directory in c:/msys/bin format
# (On other system, -W isn't a pwd flag at all.)

# (b) You *must* use the c:/ form for the -B argument, else the testsuite
