Subject: Update the non-pthreads fallback for RWMutex on Unix
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=c700c4d161f5b6bd9c655f517844ef69998b3290;p=oota-llvm.git

Update the non-pthreads fallback for RWMutex on Unix

Tested this by #if 0'ing out the pthreads implementation, which
indicated that this fallback was not currently compiling successfully
and applying this patch resolves that.

Patch by Andy Chien.
