Hi Carlo,

OK,  thanks for checking..  With 'umask = -2**31' the '-2**31' must be
interpreted
as a literal and so not allowed (of course, the whole thing is quite
weird so I'm not
sure I can predict what will work).  Anyway,
    umask = -lmask -1

it is, at least until we find a compiler that chokes on that.  Sounds
like one more
reason to stop using f77 as the sole language.
