  Try a test compile to see if PTHREAD_ONCE_INIT requires extra braces.
  
  There was conditional code (based on build platform) to optioinally wrap
  PTHREAD_ONCE_INIT in braces that was removed since it is fixed in newer versions
  of Solaris/OpenSolaris, but I am still running into it on Solaris 10 x86 so add
  a configure-time check for it.
