bug#14549: warning while compiling guile 2.0.9

[ais]

Hi Ludovic,

thanks for the reply.
The compilation did not succeed. There're several reasons behind it.
One thing is that the pthread_np.h should be avoided on OpenBSD
alltogether, since this it implements just a short fraction of functions.
So if functions from pthread_np.h should be used, then they must be tested
one by one and not assuming that if the file is present so are the
functions. I simply renamed the file "pthread_np.h" to
"pthread_np.h.original" and ran configure and this time configure
succeeded without any complaint.

The other thing with OpenBSD is, that the stock-installation of the
Boehm-GC package is more or less broken. I compiled my own version of this
library and then I could compile guile successfully, but the linker did
complain about some pthread_np* functions.
Using the stock installation/package then there's a conflict with some
defines being set (notably: GC_REDIRECT_TO_LOCAL). The stock installation
has no such file (gc_local_alloc.h) so the defines inside must be set
accordingly.

Currently I'm very busy to follow up this problem but I'm very willing to
provide more information on this topic, since I keen on having a current
version of Guile running  under OpenBSD.
