I'm also right now undecided, what I want in KDE. For now I have changed
libtool to accept -LANG. Well, it's a hack, but that's the purpose of
libtool ;) OTOH I anyway have to write a configure check, if LANG:std is
supported (and make that the default), so I can also set CPPFLAGS and
LDFLAGS appropriately in that test. This might lead to problems, if
Makefile.am authors do strange things with those vars, and in the light,
that libtool should be a better frontend (and substitute) to the compiler
I'm not too unhappy with libtool accepting -LANG.
It's anyway all SGI's fault. I really would like to know who of them had
this wonderful idea of using a flag beginning with -L for other things
then lib-paths.

Or this test is included with libtools autoconf macros.

Yep, I also like this solution most, even if this means a very special
case in ltmain.
Ciao,
