The prove.sh test fails here, because the version of 'prove' I have with MSYS is too old (1.04), and it doesn't support the -w switch. I do have 'prove' as part of the newer Perl I use with texi2any, but it's a Windows batch file, so it will be difficult to invoke that from a Bash shell script.
Do we really need the -w switch? If I remove it, the test passes.
