'''Problem 1'''. Using the Cygwin Python. `testsuite/mk/test.mk` makes
the GHC into `ghc-inplace.bat`. But `testlib.py` (the `runCmd` procedure)
invokes `timeout`, which always calls a Bourne shell, so `ghc-inplace.bat`
doesn't work.
The timeout program must use a Bourne shell, because `testlib.py` often
passes it a complex command in Bourne shell syntax.
Current workaound: in `testsuite\mk\test.mk` disable the windows-specific
setting of the GHC paths.
'''IDEA''': it's a mess having a `ghc-inplace` shell script ''and'' a
`ghc-inplace.bat` script. Instead we should have one executable, which we
can invoke from anywhere.
''PS'' Why should we care about Cygwin Python and MSYS? Well, it's
exposed a fragility with this ghc-inplace stuff; and the testsuite doesn't
work with native Python under MSYS either.
