Note that as of cabal-install-0.8, the "mkcabal" functionality is
integrated as "cabal init" (thanks to Brent Yorgey). This does not
depend on less portable packages like pcre and readline (meaning it will
work on Windows).

There's no reason pcre-light needs a configure script. It should be
removed. (It's also not used consistently, the Setup.hs is for a
different build-type than the one specified in the .cabal file).

As of Cabal-1.8 the error is reported as:

        cabal: The package has a './configure' script. This requires a
        Unix compatibility toolchain such as MinGW+MSYS or Cygwin.
