devel/ace port: thread flags issue

[Andriy Gapon]

If anybody is actively using ACE on freebsd and has time/resources to do
some port work, you might be interested.

There is an issue with using ACE default thread flags on FreeBSD with
libpthread, the issue is described and discussed in the following
message thread:
http://docs.freebsd.org/cgi/getmsg.cgi?fetch=5728+0+archive/2006/freebsd-threads/20060903.freebsd-threads

Unfortunately, neither ACE people nor ACE port maintainer participated
in the conversation, so the problem is still there.

My favorite solution would be to go with Daniel Eischen's suggestion and
to make THR_NEW_LWP an alias for THR_SCOPE_PROCESS when ACE is built on
FreeBSD. This could be done either via port patch or via OS-specific
defines of ACE code itself.
