           Summary: FAIL: staticrootslib.lo -O2 (test for excess errors)
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: dominiq@lps.ens.fr

              Host: x86_64-apple-darwin10
            Target: x86_64-apple-darwin10
             Build: x86_64-apple-darwin10


On x86_64-apple-darwin10 the test staticrootslib.lo in the boehm-gc suite fails
due to the following warnings

Excess errors:
/usr/bin/ranlib: file: .libs/libstaticrootslib.a(backgraph.o) has no symbols
/usr/bin/ranlib: file: .libs/libstaticrootslib.a(checksums.o) has no symbols
/usr/bin/ranlib: file: .libs/libstaticrootslib.a(gc_dlopen.o) has no symbols
/usr/bin/ranlib: file: .libs/libstaticrootslib.a(pcr_interface.o) has no
symbols
/usr/bin/ranlib: file: .libs/libstaticrootslib.a(pthread_stop_world.o) has no
symbols
/usr/bin/ranlib: file: .libs/libstaticrootslib.a(real_malloc.o) has no symbols
/usr/bin/ranlib: file: .libs/libstaticrootslib.a(specific.o) has no symbols
/usr/bin/ranlib: file: .libs/libstaticrootslib.a(win32_threads.o) has no
symbols

AFAICT these warnings are rather usual (I see them with 'make install' for a
lot of libraries) and they seem harmless.
