It's a problem with the MSYS Make and MSYS Bash.  They convert
command-line arguments of the form /x/foo/bar to x:/foo/bar.  This
fails miserably when the original command-line argument is not a file
name, e.g., when the Makefile invokes "cmd /c SOMETHING".  See
nt/INSTALL, which doesn't recommend MSYS for this very reason.

I see this problem even without using MSYS. I am using TDM-GCC with gcc 4.5.2 and make 3.82 and GnuWin tools. Every so often my nightly build stalls and fails with an `Access denied' error. It looks like it spawns a child cmd.exe right before. I googled and someone said make might trip up during parallel compilation so I force it with `-j 1' for testing. It still fails now and then. I will capture the exact error message and the context next time it happens.
