Is there any sane reason that:
gcc -E -dD -o - foo.c
generates ./-.exe on cygwin, rather than outputting to stdout like on
every other platform? This tripped up an autoconf test. Fortunately,
removing '-o -' appears to be portable.

I've seen that too, but didn't know that the malbehaviour of this (and iirc
also -M options) was cygwin-specific at all. Would you file a PR upstream please?
cheers,
