vms update

Browse Source 
Suppress Isaac64 on VAX were there isn't an easy way to do 64-bit
arithmetic.  (Hard way isn't worth it for just an alternate RNG.)

Eliminate or suppress some diagnostics:

1) In strict ANSI mode, DEC C was reporting that '$' in identifier is
an extension (one time for each file in sys/vms/*.c).  (It doesn't do
that for the default 'relaxed ANSI' mode.)

2) DEC C uses WIDENED_PROTOTYPES but widens uchar (unsigned char)
differently depending upon the mode it is operating in.  (Applies to
Unix as well as VMS; based on documentation rather than testing.)

Update the comment in tradstdc.h about WIDENED vs UNWIDENED_PROTOTYPES.

An old comment in config1.h about a problem with the earliest version
of DEC C was probably based on an incorrect assumption of what was
really going, but I have no way to go back in time to verify that....
