Note: GCC 2.x treats external variables differently than GCC 1.x does.
Before you use GCC 2.x, you should obtain a version of the assembler which
contains the patches to work with GCC 2.x (GCC-AS 1.38 does not contain
these patches - whatever comes after this probably will). The assembler
in gcc-vms-1.42.tar.gz from prep does contain the proper patches.

GCC 2.x treats external variables differently than GCC 1.x does. Before
you use GCC 2.x, you should obtain a version of the assembler which works
with GCC 2.x (gas-1.38 and earlier did not have the necessary support;
gas-2.0 through gas-2.3 did not work reliably for vax/vms configuration).
The assembler in gcc-vms-1.42 contained patches to provide the proper
support, and more recent versions have an up to date version of gas which
provides the support. gas from binutils-2.5 or later is recommended.
If you do not update the assembler, the compiler will still work,
If you do not update the assembler, the compiler will still work,
but `extern const' variables will be treated as `extern'. This will result
in linker warning messages about mismatched psect attributes, and these
variables will be placed in read/write storage.

-----
Note: you appear to be missing gas, the GNU assembler. Since
GCC produces assembly code as output from compilation, you need the
assembler to make full use of the compiler. It should be put in place
as GNU_CC:[000000]GCC-AS.EXE.
A prebuilt copy of gas is available from the "gcc-vms" distribution,
and the gas source code is included in the GNU "binutils" distribution.
Version 2.5.2 or later is recommended.
