Thanks Carlo,

I'll take that as a positive report and post new versions of the tar file.

FWIW, the Intel Fortran Compiler 10.0 on Wndows didn't complain at
all about umask = -2**31.  I don't know if that has any bearing on how
the Intel compiler for Unices will behave, but 'umask = -lmask - 1' does
feel right.

Cheers,
