Problems compiling when using threads.

[Mois�s Navarro Mar�n]

Hi.

    I got this error messages when compiling a multithreaded server:

/usr/lib/libpthreads.so: undefined reference to `machdep_sys_sendmsg'
/usr/lib/libpthreads.so: undefined reference to `machdep_sys_recvmsg'

    I'm compiling on OpenLinux 1.3 by Caldera.

    What's going on here?

    TIA.

    Regards from Spain.
