Configure
---------
With version 9.4 of the MKS Toolkit, configure will fail unless invoked
as

    PATH_SEPARATOR=';' configure

Compilation
-----------
The MKS version of make ignores suffix rules in Makefile unless the line

    .POSIX

appears in Makefile before any suffix rules.

The MKS versions of more and less do not recognize '+n' as an option to
display a file beginning at line n, so help <unit> from within units
will fail.  To avoid this problem, add

    -D_MKS_TOOLKIT 

to the DEFS in Makefile.
