PATCH: Support C++ and threading libraries on FreeBSD 3 and later

[Loren James Rittle]

Recently, gcc upgraded to libtool 1.4a and it came to my attention
that these system configuration patches, which had been in that tree
to better support recent versions of FreeBSD, were missing.

I first submitted them to libtool-patches back in November 2000 but I
may not have stressed their importance or that they had been approved
by multiple gcc developers and FreeBSD developers.

Could they be applied to the master libtool source tree?

Thank you,
Loren

        * ltcf-cxx.sh: Support creation of C++ shared libraries on
        recent versions of FreeBSD (release 3 or later).
        * ltconfig: On FreeBSD, -lc must not be provided when building
        a shared library or else the standard -pthread gcc option is
        rendered worthless to later users of the built library.
