> Are you appending or assigning to CFLAGS in make.conf/src.conf?
Yes,
I do. This very moment, I got rid of those messages. I think it is not
very clear to me (and maybe others) anymore, what goes into
/etc/src.conf and what is to be remaining in /etc/make.conf.
Since I wrecked all my FreeBSD 10-0-CURRENT boxes around the 15th of May
by simply building a "world" (on a daily baisis, so they got affected
all), but was luckily able to repair, I guess I need to figure out
what's really necessary to go in /etc/src.conf and in /etc/make.conf.
There are some mails in this list claiming that setting CC=3D, CXX=3D and=
CPP=3D needs also to be done in /etc/src.conf. I have those already set i=
n
/etc/make.conf using a "knob" for checking to build with CLANG or not.
Well, am I right that first /etc/make.conf gets read and then
/etc/src.conf? By mistake I set "CFLAGS=3D" instead of "CFLAGS+=3D" in
/etc/src.conf, so all settings performed prior to the "sucking in" of
/etc/src.conf got banned from the options - and ended up in not finding
even includes anymore (due to missing -Ifoo/bar options). Very tricky
and a large pithole to step into if not carefully thought about.

P.S. Most of the confusion is due to the fact I want the base OS be
built by CLANG as well as all ports which can bear being built by CLANG.
But there are those which can't yet and somehow I try to sort them out
and build them with prefereably the gcc46 or gcc47 (I use the base
systems USE_GCC=3D4.6+ option).
For this purpose, I include at the end of /etc/make.conf a file named
ports.conf like this:
=2Einclude "/usr/local/etc/ports.conf"
The content of ports.conf is like:
[...]
# mail/thunderbird
=2Eif ${.CURDIR:M/usr/ports/mail/thunderbird}
USE_GCC=3D 4.6+
#CC=3D cc
#CXX=3D c++
#CPP=3D cpp
CFLAGS+=3D -DLDAP_DEPRECATED
CXXFLAGS+=3D -DLDAP_DEPRECATED
=2Eendif
[...]
This approach does only work, if the not well documented knob
"WITH_CLANG_IS_CC" is not set, so cc stays with the legacy gcc 4.2.1.
By the way, I would like to see a much more restrictive way to separate
the FreeBSD core system from ports in a logical way. Either I have a
great misunderstanding and this is already the fact, or ...
