+# 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.)

+# Explicit dependencies
+
+# Some .hs files #include other source files, but since ghc -M doesn't spit out
+# these dependencies we have to include them manually.
+
+# We don't add dependencies on HsVersions.h, ghcautoconf.h, or ghc_boot_platform.h,
+# because then modifying one of these files would force recompilation of everything,
+# which is probably not what you want. However, it does mean you have to be
+# careful to recompile stuff you need if you reconfigure or change HsVersions.h.
+
+# Aargh, these don't work properly anyway, because GHC's recompilation checker
+# just reports "compilation NOT required". Do we have to add -no-recomp for each
+# of these .hs files? I haven't done anything about this yet.
