# MSys notes
# Note 1
# 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.)

# Note 2
# On MSys, we must use the following script for ghc-inplace:
# exec /c/darcs/fc-branch-2/compiler/stage1/ghc -Bc:/darcs/fc-branch-2 "$@"
# That is,
# (a) You *must* use the /c/ form for the first arg to exec. Using the
# c:/ form makes exec complain that it can't find $pwd/c:/darcs/.../ghc
# The /c/ form is $(FPTOOLS_TOP_ABS)
# (b) You *must* use the c:/ form for the -B argument, else the testsuite
# doesn't work. I think that's something to do with ghc-inplace being
# invoked by Python
# The c:/ form is $(FPTOOLS_TOP_ABS_PLATFORM)
