Static linking libpthread doesn't work without it. The following
commands work with the patch:
$ echo 'int main(){return 42;}' | i686-pc-gnu-gcc -pthread -xc -
$ echo 'int main(){return 42;}' | i686-pc-gnu-gcc -static -pthread -xc -
Without the patch, the second command fails:
$ echo 'int main(){return 42;}' | i686-pc-gnu-gcc -pthread -xc -
$ echo 'int main(){return 42;}' | i686-pc-gnu-gcc -static -pthread -xc -
/usr/i686-pc-gnu/sys-root/lib/libcrt.a(cthreads.o): In function
`__libc_getspecific':

/usr/i686-pc-gnu/sys-root/lib/libpthread2.a(cthreads-compat.o):(.text+0xd0):

collect2: error: ld returned 1 exit status
There may have been other subtle issues with running X or xdm from
this, but I might be thinking of an earlier bad workaround I had... I
also didn't comment enough to remember the whole story.
Thanks.
