$! Command file to build libgcc2.olb.  You should only run this once you
$! have the current compiler installed, otherwise some of the builtins will
$! not be recognized.  Once you have built libgcc2.olb, you can merge this
$! with gnu_cc:[000000]gcclib.olb
$!
$! All of the C source code is assumed to be in libgcc2.c, and a list of the
$! modules that we need from there is in libgcc2.list (which is generated
$! when vmsconfig.com is run).  The C++ source is found in the [.cp.inc]
$! directory and managed via libgcc2-cxx.list.
