$!
$! First we figure out what needs to be done. This is sort of like a limited
$! make facility - the command line options specify exactly what components
$! we want to build. The following options are understood:
$!
$! LINK: Assume that the object modules for the selected compiler(s)
$! have already been compiled, perform link phase only.
$!
$! CC1: Compile and link "C" compiler.
$!
$! CC1PLUS:Compile and link "C++" compiler.
$!
$! CC1OBJ: Compile and link objective C compiler.
$!
$! ALL: Compile and link all of the CC1 passes.
$!
$! INDEPENDENT:
$! Compile language independent source modules. (On by default).
$!
$! BC:
$! Compile byte compiler source modules. (On by default).
$!
$! DEBUG: Link images with /debug.
$!
$! If you want to list more than one option, you should use a spaces to
$! separate them.
$!
$! Any one of the above options can be prefaced with a "NO". For example,
$! if you had already built GCC, and you wanted to build G++, you could use the
$! "CC1PLUS NOINDEPENDENT" options, which would only compile the C++ language
$! specific source files, and then link the C++ compiler.
$!
$! If you do not specify which compiler you want to build, it is assumed that
$! you want to build GNU-C ("CC1").
$!
$! Now figure out what we have been requested to do.

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.
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.
