1.38 +I have been testing following patch on hammer.
1.39 +linuxthreads built just fine and NPTL libraries too,
1.40 +and in both cases libraries had the same exported symbols as without
1.41 +the patch (though its .text slightly shrunk because it no longer contained
1.42 +unneeded libgcc_eh routines (and also libc.so has fewer .plt slots).
1.43 +Unfortunately, sln in NPTL build doesn't link, as libgcc_eh.a is needed
1.44 +in this case.
1.45 +So, IMHO we need my Makerules change and Daniel's patch.
