configure loads its cache file at startup; as of autoconf 2.5x, the
cache file defaults to /dev/null (i.e. cache disabled).
So it runs ". /dev/null", which in our bash gives:

 $ . /dev/null
 bash.exe: .: /dev/null: not a regular file

Normally, this is fine, because configure first uses 'test -f' to
ensure it IS a regular file.  Unfortunately, our bash's 'test -f'
thinks it IS a regular file, while its '.' doesn't.
