Please make a point of telling this in the future.  I have no way of
knowing when you make such changes, and they add more confusion to
this already complicated issue.

If you invoke the above command from the MSYS Bash prompt, does it
also fail in the same way?

What about this variant:

 test "$MSYSTEM" = "MINGW32" && srcdir=`(cd "$srcdir"; pwd -W | sed -e 's,^\([A-Za-z]\):,/\1,')`

It should produce srcdir in the /d/foo/bar format.

Sorry, I don't have time for this.  If the above still does not work,
then for now, building under the MSYS root will be unsupported, until
someone figures a way of making it work and submits the necessary
patches.
