Hi,

I'm testing postgresql 8.5 alpha3 on OpenBSD (-current , amd64 and macppc).
The port uses the option --libxml.

With this option, I have the following error:

[...]

checking whether pthreads work without any flags... no
checking whether pthreads work with -Kthread... no

configure: error: thread test program failed
This platform is not thread-safe.  Check the file 'config.log' or compile
and run src/test/thread/thread_test for the exact reason.
Use --disable-thread-safety to disable thread safety.



*OpenBSD must use -pthread.*

The config.log shows me these lines:

When I remove the option --libxml in the port, everything is ok.

Please note that both -pthread and -lpthread are on yes now.

And the config.log:

Your errno is thread-safe.
Your system has sterror_r();  it does not need strerror().
Your system has getpwuid_r();  it does not need getpwuid().
Your system has getaddrinfo();  it does not need gethostbyname()
  or gethostbyname_r().

Your platform is thread-safe.

I don't understand why the detection of both -pthread and -lpthread fails with --libxml (may 
the messages about strcpy/strcat be the cause) ?

Regards,
