[mercury-users] Intermittent problems with building Mercury

[Jonathan Morgan]

I have had problems under Cygwin compiling both 0.12.0 and 0.12.2, but not
0.12.1 (see error message below).  These problems first cropped up after I
had installed 0.12.0, and then extracted a clean copy to a different place
to test the IL backend.  The clean copy came up with these problems, but a
copy of the directory I had installed from always worked, even after running
mmake clean.  0.12.1 was fine, but these problems have come up again with
0.12.2.  What do I do about it?
