The configure script first tries to compile a test programm without the
'-package parsec', this succeeds with GHC-6.5 because the test program
only imports parsec, but doesn't use it.
On the other hand, with GHC-6.4 the first compile without '-package parsec'
fails and the package flag is added to GHCFLAGS in autoconf because of that.
