(I thought host_alias was the "official" variable to use there, along
with {build,target}_alias)

You can set the triplet explicitly, but the whole purpose of
config.guess is to save you the trouble. Given that the script already
does the right thing on e.g. Solaris if it notices CC with 64-bit flags,
do you see a way that it can similarly get things right if CC is set to
the MinGW compiler on Cygwin?

(I recognize that the MinGW compiler now takes the form of a cross-
compiler, and that's great, but whether or not Autotools uses it as
a cross compiler is independent of that. After all, if you had an
old-style package with a standalone makefile, and you wanted to
build using the MinGW compiler, you'd have to set CC/CXX/CFLAGS in a
non-cross-ish way.)

So far, it seems that building with host==build==i686-pc-mingw32 on
Cygwin breaks only because of that "cmd //c" thing in Libtool.
