new cygwin 1.7 functions

[Eric Blake]

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I'm pushing this.  cygwin 1.7 will also be adding fpurge and mkstemps, but
glibc doesn't provide either, so I don't know where to document them
(glibc provides __fpurge rather than fpurge, and there is an open bug
report to have glibc add mkstemps).

Don't work too hard, make some time for fun as well!
