Howdy,

When I try to compile guile 1.8.0 on QNX 6.3.0, it fails as follows:

> source='threads.c' object='libguile_la-threads.lo' libtool=yes \
> DEPDIR=.deps depmode=gcc /bin/sh ../depcomp \
> /bin/sh ../libtool --tag=CC --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I.. -I.. -I..  -I/usr/local/include  -g -O2 -Wall -Wmissing-prototypes -c -o libguile_la-threads.lo `test -f 'threads.c' || echo './'`threads.c
>  gcc -DHAVE_CONFIG_H -I. -I. -I.. -I.. -I.. -I/usr/local/include -g -O2 -Wall -Wmissing-prototypes -c threads.c -Wp,-MD,.deps/libguile_la-threads.TPlo  -fPIC -DPIC -o .libs/libguile_la-threads.o
> threads.c:1401: conflicting types for `unlock'
> /usr/qnx630/target/qnx6/usr/include/unistd.h:490: previous declaration of `unlock'

The attached patch renames the unlock function in threads.c to
static_unlock, which fixes the problem.

Thanks, will be in CVS very shortly.
