So I tested on F19 with this series applied and hit a small problem

In file included from util/virstoragefile.h:28:0,

The problem seems to be our recently added configure.ac check from

build: fix build on mingw with winpthreads
The F19 pthreads.h does not define any pthread_sigmask function,
so our configure check fails and activates our dummy wrapper in
virutil.h. Unfortunately gnulib has also detected the missing
pthread_sigmask and provided its own wrapper in signal.h and thus
we clash. We need to somehow make our configure.ac check detect
distinguish missing pthread_sigmask from broken pthread_sigmask
