Fair point.
But pragmatically we are not any worse off, and at least we are in a better
position than if we reverted the pass through patches. Later in the thread
I propose that we can try to maintain a list of argument options that need to
be passed through, and fall back to mangling (with a bug-libtool nag) when we
don't provide any other way for the user to get options to the compiler (until
the next release if they report it)...
Cheers,
Gary.
