  New Revision: 48095

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=48095

  Log:
    Fix PNaCl configure/link errors.
    
    * configure.in (nacl_cv_cpu_nick): fix typo in PNaCl.
      (XCFLAGS) Add -isystem flag to pnacl and nacl-newlib
      (CXX): added
    
    * nacl/GNUmakefile.in (CXX): Added
      (PPROGRAM): Use clang++ instead of clang because libnacl_io
      depends on c++ std lib.
