Experience: tested the Pascal VS [Sale 1978 on] on the Univac 1100 series
compiler, and used the FCVS on both the Cray Y-MP and ETA-10Q.  Am fully
aware of the ACVS, and a few developments which aren't public. I was an
ANSI committee member [not the same as an ANSI member].

Jeff, the FCVS doesn't do anything as sophisiticated as unaligned accesses.
It merely tests for comformance to a standard (ANSI...1978).  The Pascal VS
had a bit more.  ACVS is a considerably more rigourous than either.
There are a few clever things, but nothing as clever as I was once told.

Standards are simply pieces of paper which are gentleman's agreements.
They aren't blueprints.  Standards are typically after the fact documents.
Don't expect every machine and compiler to pass.  These test are not
cut and dry.  They are not strictly all pass-fail.

Another gross generalization from
