+$! have the current compiler installed, otherwise some of the builtins will
+$! not be recognized.  Once you have built libgcc2.olb, you can merge this

+$! All of the C source code is assumed to be in libgcc2.c, and a list of the
+$! 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.
