Let's turn the question around: Do you think it would be a more
maintainable approach to go with what Libtool uses in its compile/link
tests: namely, compare stderr output contents without and with the flag
to try out?

This is a tricky question!  The linker that MSVC calls actually manages
to print its arguments; or it's cl doing that when calling the linker.
Seems on stdout though, judging from your recent "MSVC status" mail on
a libtool list.

Does cl have a -Werror sort of flag that causes its exit status to be
usable for setting other flags?

Thanks,
Ralf
