On my Fedora 20 box with mingw cross-compiler, the build failed with: ../../src/rpc/virnetclient.c: In function 'virNetClientSetTLSSession': ../../src/rpc/virnetclient.c:745:14: error: unused variable 'oldmask' [-Werror=unused-variable] sigset_t oldmask, blockedsigs; ^ I traced it to the fact that mingw64-winpthreads installs a header that does #define pthread_sigmask(...) 0, which means any argument only ever passed to pthread_sigmask is reported as unused. This patch works around the compilation failure, with behavior no worse than what mingw already gives us regarding the function being a no-op. * configure.ac (pthread_sigmask): Probe for broken mingw macro. * src/util/virutil.h (pthread_sigmask): Rewrite to something that avoids unused variables.
