Indeed it was.  I've been booting my CLFS system at the end of chapter
7 as a Xen virtual machine.  I'd added Xen, emacs, zsh, and a lots of
other goodies to my host system by installing them in my homedir.
Anything that uses pkg-config works just fine after adjusting
PKG_CONFIG_PATH... but things that don't install .pc files need
CPPFLAGS and LDFLAGS set in order for configure scripts to find them.
You see where this is going.  ;-)

I was logged in as my normal user, and had just parsed the clfs user's
settings into my environment.

Was doing neither, admittedly.  I've been doing these builds on and
off for 10+ years and got brave/crazy/lazy.  And I got exactly what I
deserved.  :-/

Your call.  But why unset CFLAGS and CXXFLAGS w/out also unsetting
CPPFLAGS?  Neither CFLAGS or CXXFLAGS would be set at that point
either, if I'd been the clfs user.
