Summary:                    [patch] Failure to include semaphore.h breaks
compilation with >2.6.34 kernels (2.6.35-rc0)
Description: 
DAHDI relied on other headers to drag in semaphore.h, this is no longer the
case since:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=3142788b7967ccfd2f1813ee9e11aeb1e1cf7de2

The result is:
In file included from
/var/tmp/portage/net-misc/dahdi-2.3.0/work/dahdi-linux-2.3.0/drivers/dahdi/voicebus/GpakApi.c:36:
/var/tmp/portage/net-misc/dahdi-2.3.0/work/dahdi-linux-2.3.0/drivers/dahdi/voicebus/GpakCust.h:114:
error: field ‘sem’ has incomplete type

Patching the header to include semaphore.h as it should always have done
will not hurt older kernels.

Okay, will make it conditional. Do we know when semaphore.h was introduced?
