Robert,

Sorry, I'm not sure I understand everything you said--forgive my ignorance.
I'm not sure what you mean by 'the tag' in this context.

I'm also not sure how I can get a more recent libtool than HEAD.... or did I
not get what I thought I got?  Should I be checking out an untagged cvs
version?

So the assumption is that $CC = $CXX when using C++?  This is not always true.
While for the simple project in question it _could_ be, this seems a blatant
misuse of $CC.  Otherwise, why have $CXX at all?

Plus, autoconf makes those distinctions for me (and most people that use
libtool are using autoconf, aren't they?).

As far as submitting a patch to m4, I assumed it would always be rejected since
C++ support is unofficial.  Plus, the compiler is GCC which surely is
supported.

Thanks for the help.  I guess I'll have to decide whether to continue hacking
libtool or to mess up what I consider to be the proper use of $CC.

The question is mostly moot as I can't move more complex projects to libtool
due to the fact that it always compiles source files twice.  When using the STL
and C++, this can take a LONG time... anyone know how to tell libtool that the
object files I'm generating are all PIC, and as such the .o and .lo files are
bitwise identical?
