After I upgrade to 6.6.1 (using OS X on PPC) then I will make new versions of
regex-compat and regex-tdfa.  The thing I have to fix is that the current
"unstable" regex-tdfa depends on the "unstable" regex-base and I have to make a
new branch of regex-tdfa that works against the "stable" regex-base that 6.6 and
6.6.1 use.  Mainly this will be erasing code.

For 6.8 we can upgrade regex-base to whatever the latest version is then.
Current changes in regex-base are (1) use of 'fail' for error handling in
RegexMaker, (2) use of newtypes to make avoid Hugs seeing overlapping instances
in RegexContext (no more conditional compilation).
