The code in kdecore/util/kshareddatacache* does not build on
OpenSolaris b134 with Sun Studio 12u1.
It ends up with
...
"/export/home/test/Dashboards/kdelibs/srcdir/kdecore/util/kshareddatacache_p.h",
line 346: Error: Type name expected instead of "pthreadTimedLock".

The checks for the features are not in line with what we have in Open/Solaris.
While http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/head/unistd.h
defines
_POSIX_TIMEOUTS to 200112L in all cases, it only defines
_POSIX_THREAD_PROCESS_SHARED	 to 200112L for XPG6 (C), while for XPG5
(C++) it is defined to 1.
So we end up with KSDC_TIMEOUTS_SUPPORTED and
KSDC_THREAD_PROCESS_SHARED_SUPPORTED undefined (and pthread.h not
included!). This causes the error.

I'm no expert in any threads, so I am not sure whether to add
KSDC_THREAD_PROCESS_SHARED_SUPPORTED to the ifdef at line 344
(limiting ourselves as MacOS does, or to modify the checks at line 42
to enable the feature for us.

Hints more than welcome
