             Bug #: 51470
           Summary: [4.7 regression] make sure libgcj_bc=yes iff
                    enable_shared=yes
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libgcj
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: jojelino@gmail.com
              Host: i686-pc-cygwin

Created attachment 26029
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26029
preprocessed fix

i tried to configure libjava, but generated config.status had strange
configuration.
S["USE_LIBGCJ_BC_FALSE"]=""
S["USE_LIBGCJ_BC_TRUE"]="#"
S["ENABLE_SHARED_FALSE"]="#"
S["ENABLE_SHARED_TRUE"]=""
why this happened? i saw this in libjava/configure.ac
if test "$enable_shared" != yes; then
  use_libgcj_bc=no
fi
there isn't any declaration about use_libgcj_bc, so use_libgcj_bc would default
to  no.
here is proposal to fix the problem.

Now it's invalid.
## This is specific to Linux/{Free,Net,Open}BSD/Hurd and perhaps few others.
## USE_LIBGCJ_BC shouldn't be set on other targets.
