Wierd. It's been a while since I updated my local svn tree of gcc. It
finally finished, and I see that, in fact, current gcc trunk includes a
much newer version of libtool than I thought (2008-09-26==2.2.6ish, not
2007-03-18). So, in reality, *current* gcc libtool has the "new" behavior.
If that's working for you, Danny, then I guess gcc really did "dodge the
bullet" -- maybe libtool is never used in linking applications or test
progs within the gcc tree, so it's a moot point /for gcc/?
But, all the worries I listed still apply for *other* packages that
someone might want to compile using --build=mingw --host=mingw, when
$build is actually cygwin. But it'd be wonderful to avoid all that
worry for the src/ tree!
