>Description:

patch-AA from port patches contains uncompleted 8bitization patch which
changes size of bit table for character class in real but doesn't change
its declaration. As result, regexp matching works unstable.

>How-To-Repeat:

E.g. for string "23.203", "^[0-9]" matches; "[0-9]*" doesn't;
"^([0-9][0-9.]*)" matches again. There are another examples of unstable work
but code is more eloquent.

>Fix:

Apply the following patch to the port:

diff -rNu 0/usr/ports/net-mgmt/netmond/files/patch-AA 1/usr/ports/net-mgmt/netmond/files/patch-AA
