mknod on OSF/1

[Bruno Haible]

On OSF/1 with g++, I'm seeing this error in the test suite:

depbase=`echo test-glob-c++.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`; g++ 
-DHAVE_CONFIG_H -I.   -DGNULIB_STRICT_CHECKING=1  -I. -I.  -I.. -I./..  
-I../gllib -I./../gllib -mieee   -MT test-glob-c++.o -MD -MP -MF $depbase.Tpo 
-c -o test-glob-c++.o test-glob-c++.cc && mv -f $depbase.Tpo $depbase.Po
In file included from ../gllib/glob.h:34,
                 from test-glob-c++.cc:22:
../gllib/sys/stat.h:865: error: invalid conversion from 'int (*)(const char*, 
mode_t, ...)' to 'int (*)(const char*, mode_t, dev_t)'
*** Exit 1

The reason is that 'mknod' is declared as
  extern int mknod (const char*, mode_t, ...);
whereas gnulib expects
  extern int mknod (const char*, mode_t, dev_t);

This fixes it.

        mknod: Avoid error in C++ mode on OSF/1 with GCC.
        * lib/sys_stat.in.h (mknod): Use _GL_CXXALIAS_SYS_CAST instead of
        _GL_CXXALIAS_SYS.
