Hello,

I just returned to the office (and related e-mail).

Objective-C is enabled by default for FreeBSD in the FSF source
release.  It has been for as long as I can remember.

It is my understanding that Objective-C++ is not enabled by default
for any platform.  I do not know if it even builds for FreeBSD.

According to gcc/objcp/config-lang.in :

# Per GCC Steering Committee.
build_by_default="no"

Therefore either:

(1) You need to manually configure with --enable-languages=obj-c++

(which I think could be enabled by a FreeBSD port collection knob with
a default of "no" to honor the request of the GCC Steering Committee)

(2) Contact a member of the GCC Steering Committee to understand why
the default is as such and whether an OS port collection may override
the default.

Sorry, I don't know the history here.

Regards,
Loren
