After the following change the Lrs-race test case starts to intermittently
fails:
eac65dc Add basic support for the QNX operating system
When we include "config.h" into the "libunwind_i.h" we undefine
the HAVE___THREAD macro in a few lines below in #include "config.h"
pragma. The change eac65dc includes "config.h" into the "dwarf.h"
but forgets to undefine HAVE___THREAD. So now this macro has inconsistent
state among the code. Somewhere it is defined, somewhere not. In particular
it becomes defined in the mi/Gset_caching_policy.c and we do not replace
UNW_CACHE_PER_THREAD caching policy by the UNW_CACHE_GLOBAL.
The fix is rather dirty. It adds the code to undefine HAVE___THREAD in
the "dwarf.h" like we do that in the "libunwind_i.h". Probably the ideal
solution should fix per-thread caching implementation or turned it off
at all on platforms where it is not completely and correctly supported.
