For a start, I just applied a patch to the new regex functions.  I used
the test file from Henry Spencer together with the test application
from glibc, and the results were hair-raising.  I did practically
nothing else today but to debug this and to minimize the problems with
this regex implementation, especially in the multibyte cases.  AFAICS
there are no really bad problems left.  Makes me wonder if this code was
really tested at all in FreeBSD :(
