When I tried to bootstrap mainline on Solaris 10/x86 with the (still
unreviewed) boehm-gc patch
http://gcc.gnu.org/ml/java-patches/2007-q2/msg00304.html
I noticed that i?86-pc-solaris2* is affected by PR libgcj/30513, too. The
following patch fixes this.
Unfortunately, libgcj.so fails to link since many object files contain
non-PIC code even when compiled with -fPIC. I'll have to investigate this.
Ok for mainline after the lockdown?
