Also, on Alpha, vms.mar is no longer used (it produced a lot of
confusing messages) for BN.  Instead, the assembler part of bn_lcl.h
is used.

what is known about VAX and Alpha running VMS, and from the
opensslconf.h.in (in VMS often named OPENSSLCONF.H_IN) file.

Add info about where to get MASM.

Rebuild error files.

single fault:-) Needless to mention that bnbug.c posted couple of days
ago passes as well...

where the new functions are mentioned.

backup will complain about some version not existing.  Perhaps.

files, unless it's all in unixly syntax.  We can't guarantee that
right now, so let's skip the whole test suit.  There are other places
(like the open()) where errors are detected anyway.

patch.

(they don't really exist before version 7), so that solution was toast.
Instead, let's do it the way it's done on Unix, but then remove older
versions of the file.

That new mechanism *may* fail for some unixly formated file spec,
although I wouldn't worry too much about it.

Actually, this should be resolved by using size_t a bit more, but
that'll be for later.

also needed to get around C compilers on VMS that set the symbol limit
to 31 characters.  Bot the macros VMS and __VMS are checked, since
there's no real way to know if e_os.h has been included yet.
