According to documentation, perl's Math::BigInt does floored division,
i.e. the bdiv function does 1 / -4 = -1.  OpenSSL's BN_div, as well as
bc, do truncated division, i.e. 1 / -4 = 0.

We need to compensate for that difference in test/recipes/bc.pl to
make sure to verify the bntest results under its own conditions, by
dividing the absolute values of the given numbers and fixup the
result's negativity afterwards.

These logical names are used to make the C RTL change certain
behaviors, sometimes to make it act more like Unix.  While they can
make life easier in some cases, they can be disruptive as well.  When
building and testing OpenSSL, the latter is the case, so we ask people
to avoid using them.

On Windows and Unix, the staging directory $(DESTDIR) can simply be
prepended to the installation directory.  An attempt was made to do
something similar on VMS, but that ended up being a half measure
solution.  Instead of that, simply use the staging directory as a
prefix under which [.OPENSSL-INSTALL] and [.OPENSSL-COMMON] will hold
the two directory trees that should end up in the directories
indicated by --prefix and --openssldir, and finish the installation
with appropriate instructions on what to do next.

In this OpenSSL version, we deliver engines with lower case symbol

Sometimes, you might end up with a rather long compile line due to
excessively long /INCLUDE directories.  Compensate for it by making
a temporary logical name with them and using said logical name as
/INCLUDE argument.

A note was added to NOTES.VMS regarding these limitations.
