Berkeley Regex - was: fixincludes jumbo patch 2

The good news is that earlier objections about incompatibilities
between GPL and the Berkeley license don't apply anymore, see

ftp://ftp.cs.berkeley.edu/pub/4bsd/README.Impt.License.Change

GPL requires that no additional restrictions may be made, and the only
additional restriction in BSD code has been revoked. I don't know for
sure whether the regex code falls under this rule, but I guess it
will.

Of course, you cannot expect the authors of this code assign their
copyright to the FSF, which might be a problem for inclusion into GCC.
The same problem would occur with any other general-purpose regex
engine that is not already copyright by the FSF.
