1.4 +See http://gcc.gnu.org/PR11903

1.6 +Patch to fix following test case failure:
1.7 +
1.8 + === libstdc++-v3 tests ===
1.9 +FAIL: thread/pthread1.cc (test for excess errors)
1.10 +Excess errors:
1.11 +/opt/cegl-2.0/sh4-unknown-linux-gnu/gcc-ss-3_3-20030714-glibc-2.2.5/sh4-unknown-linux-gnu/bin/ld: cannot find -lthread
1.12 +collect2: ld returned 1 exit status
1.13 +
1.14 +Note that *any* program compiled with -pthread fails:
1.15 +
1.16 +/opt/cegl-2.0/sh4-unknown-linux-gnu/gcc-ss-3_3-20030714-glibc-2.2.5/bin/sh4-unknown-linux-gnu-gcc hello.c -pthread
1.17 +/opt/cegl-2.0/sh4-unknown-linux-gnu/gcc-ss-3_3-20030714-glibc-2.2.5/lib/gcc-lib/sh4-unknown-linux-gnu/3.3.1/../../../../sh4-unknown-linux-gnu/bin/ld: cannot find -lthread
1.18 +collect2: ld returned 1 exit status
1.19 +
1.20 +Compiling with -lpthread on the other hand works fine:
1.21 +/opt/cegl-2.0/sh4-unknown-linux-gnu/gcc-ss-3_3-20030714-glibc-2.2.5/bin/sh4-unknown-linux-gnu-gcc hello.c -lpthread
1.22 +
1.23 +So -pthread is broken in some trivial way; it should invoke -lpthread, not -lthread,
1.24 +at least when targeting Linux.
1.25 +
1.26 +http://www.sh-linux.org/rpm-2003/SRPMS/gcc-3.2.3-3.src.rpm contains a jumbo patch,
1.27 +gcc-20030210-sh-linux-1.patch, that includes a fix for this. Here's the
1.28 +appropriate hunk (brings in a fix for the documented -mieee option).
1.29 +No idea if this fix is completely right, but it works for me...
