FAIL: thread/pthread1.cc (test for excess errors)

Excess errors:

/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

Note that *any* program compiled with -pthread fails:

Compiling with -lpthread on the other hand works fine:
|
|
yann@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 -lpthread
|

So -pthread is broken in some trivial way; it should invoke -lpthread, not -lthread,
|
|
yann@1
|
19 |
at least when targeting Linux.

http://www.sh-linux.org/rpm-2003/SRPMS/gcc-3.2.3-3.src.rpm contains a jumbo patch,
|
|
yann@1
|
22 |
gcc-20030210-sh-linux-1.patch, that includes a fix for this. Here's the
|
|
yann@1
|
23 |
appropriate hunk (brings in a fix for the documented -mieee option).

No idea if this fix is completely right, but it works for me...
