Ok, I'll try that.
BTW: The libtool in question is a GNU libtool, but it isn't the Apple
supplied libtool, it comes with the apache distribution.
Thanks.

Hmmm ... the problem is that this is actually an apache module
built by apxs, which in turn uses their own libtool (in $PREFIX/
build) to do the actual linking.
Are there any LDOPTS I can pass to make ld be in "C++" mode?
ld doesn't know about either C or C++. More specifically, it
doesn't know which files the compiler needs for all of the various
options which can be passed. That's why linking with gcc or g++ is
recommended (and I think libtool typically does exactly that).
I guess I can edit the libtool script, but then I'm not sure I'll
be able to compile C-only modules anymore!
They'll work. You can use g++ to build C code; it'll just link in
some unnecessary C++ stuff.
