That covers MSYS/Cygwin, since they ARE POSIX.
This change affects autoconf macros, and on Wind..no, scratch that...on
POSIX they are used by stuff running under POSIX (which, in our case,
is Cygwin or MSYS). I don't see a problem here. We always assume that
autotools == POSIX system or a POSIX layer on top of non-POSIX system.

You can (obviously) use autotools to build things other than
libgcrypt, and you do this on POSIX (which could be a compatibility
layer). And you might want to be able to substitute stock POSIX tools,
or alter their invocation somehow (i do that to the STRIP tool every
time i build something), when building stuff on POSIX and configuring
using the macros libgcrypt provides.

I fail to see any problem with this (other than maybe a
misunderstanding about what "on Windows" means for people who build
free software packages VS what it means for you personally).
