I noticed that TestGtkEmbed which I built is not linked to pth-2.0.3.

In build log, I can see:

  checking for pthread_create in -lpthreads... no
  checking for pthread_create in -lpthread... no
  checking for pthread_create in -lc_r... no
  checking for pthread_create in -lc... no

Any pthreads library is not appeared in result of `ldd TestGtkEmbed':

  TestGtkEmbed:

         -lstdc++.4 => /usr/lib/libstdc++.so.4
         -lc.12 => /usr/lib/libc.so.12

It seems that configure searches pthreads library only in
`-lpthreads', `-lpthread', `-lc_r' and `-lc' not but in `-lpth' and It
seems that TestGtkEmbed which I built don't use any pthreads
libraries, but it woks fine.

So it may be good effect for building minimo to add `ac_add_options
--without-pthreads' on NetBSD-2.0 which has native pthreads library ?
