[Gm2] Solaris10 and OS 10.4 woes with gm2 of 2008-07-10

[John O Goyo]

Something on Solaris 10/sparc compiled with the latest version
(2008-07-10) no longer ran.  I investigated and discovered a small
test case, as illustrated in the following session.

    output.Init

    InOut.WriteLn

Neither the debug information nor even the call seems to be linked
into the main module.  The truly odd thing is that I found exactly the
same problem under OS 10.4/PPC (below).
