I worked up a patch to always build libstdc++ with -Wabi, and then thought
that perhaps all C++-using target libraries should have this on. What are
people's thoughts on this?
The easiest way, I think, would be to pass it as part of the toplevel
configure.in's CXX_FOR_TARGET.

Yes, it's a good idea.

Someone else will have to do it. I have been defeated by toplevel configury.
- Makefile.in sets and passes both CXXFLAGS_FOR_TARGET and
LIBCXXFLAGS_FOR_TARGET, but in target libraries, sets CXXFLAGS to the
first, not the second. I don't know what the second variable is meant
to be used for, given that it /isn't/ used even though all the targets
are libraries.
- Adding -Wabi to CXXFLAGS_FOR_TARGET doesn't change anything, because the
assignment on line 141 of Makefile.in is later overridden (not appended
to) by a fragment inserted into the generated Makefile. I don't know
which fragment or where it comes from. The variable is not documented as
"this is substituted by configure," so this took a while to debug.
