GCC 4.1.0 C++ broken for threading on OpenBSD 3.9.

[Karel Gardas <kgardas at objectsecurity dot com>]

Hello,

I've looked into the bugzilla, but have not been able to find similar or 
the same bug, so I wonder if this is known or not. Anyway, when I compiled 
GCC 4.1.0 (release) on OpenBSD 3.9 configured with:

$ c++41x -v
Using built-in specs.
Target: i386-unknown-openbsd3.9
Configured with: /home/karel/build/gcc-4.1.0/configure 
--prefix=/home/karel/usr/local --program-suffix=41x --enable-threads 
--enable-shared --disable-checking --enable-languages=c,c++
Thread model: posix
gcc version 4.1.0
$

I've got "broken" C++ compiler (or perhaps libstdc++/libgcc), since if I 
try compiling simple C++ hello world example I get a lot of POSIX threads 
related unresolved symbols coming from libstdc++ and libgcc (see below).

The simple workaround is to add -lpthread for linking phase, but IMHO this 
is a bit inconvenient and probably shouldn't be required.

Question is: shall I report this to bugzilla?

Thanks,
Karel
