The old raw format can't be handled by some implementations
and updates to RFC2560 will make this mandatory.

Don't read past end of total data available when -offset supplied.

If -length exceeds total available truncate it.

let's check for those macros, and if they aren't defined, let's assume
there aren't Unixly devices on this platform.

automatically to accomodate the value, some compilers fail to do so. Most
notably 0x0123456789ABCDEF should come out as long long in 32-bit context,
but HP compiler truncates it to 32-bit value. Which in turn breaks GF(2^m)
arithmetics in hpux-parisc2-cc build. Therefore this fix...

VMS.  The C RTL can handle it well if the "directory" is a logical
name with no colon, therefore ending being 'logname/file'.  However,
if the given logical names actually has a colon, or if you use a full
VMS-syntax directory, you end up with 'logname:/file' or
'dev:[dir1.dir2]/file', and that isn't handled in any good way.

So, on VMS, we need to check if the directory string ends with a
separator (one of ':', ']' or '>' (< and > can be used instead [ and
])), and handle that by not inserting anything between the directory
spec and the file name.  In all other cases, it's assumed the
directory spec is a logical name, so we need to place a colon between
it and the file.
