compile.sh appears broken in MSYS2

[mrdomino]

This is on a clean install of MSYS2 plus the dependencies listed on the windows page. It's on Windows 8.1 Pro. Tested on 3fe87d7 as well as a couple earlier commits. Fwiw that file does exist (with the slashes the other way around, from msys's perspective) in the tmp directory.

$ ./compile.sh

A workaround is to do smth like:
export TMPDIR=c:/temp
then msys's path mangling^W "correction" will not kick in.

I'll claim that this is a duplicate of #276.
