Certainly not a typo in binuti

The VMS port of the Intel's assembler is freely downloadable by HP
partners but is only accessible by HP customers through their HP
partner. The HP OpenVMS group which ported this Intel's assembler
seems to have added the -Nvms_upcase option to it and when not
specified all global names are uppercased. This matches the default
behavior of all HP compilers.

The GNU assembler on VMS processes global symbols as is. This matches
most GNU compilers default behavior, except gfortran which processes
all global names as lowercase characters adding a trailing underscore
unless -fno-underscoring option. The Adacore's GNAT Ada Pro product on
VMS product have an /UPPERCASE_EXTERNAL option to fit with HP
compilers generated code. I did not check calling GNAT Ada Pro VMS/Ada
code from HP Fortran for OpenVMS, focusing on this casing aspect. More
narrowing this casing problem, I did not check whether
/UPPERCASE_EXTERNAL also means /UPPERCASE_GLOBALS.

A perhaps suggestion to the binutils GNU assembler developers would be
to add a VMS specific --uppercase-globals so that assembly routines
may be called from case insensitive HP compilers such as Cobol,
Fortran, Basic, Pascal or, when no /names=(as_is) added qualifier, by
the HP C and HP C++ compilers.
