Akim Demaille bc96b757ca yacc.c: fix warnings about undefined macros ...

For instance with GCC 4.9 and --enable-gcc-warnings:

    25. input.at:1201: testing Torturing the Scanner ...
    ../../tests/input.at:1344: $CC $CFLAGS $CPPFLAGS  -c -o input.o input.c
    stderr:
    input.c:239:18: error: "__STDC_VERSION__" is not defined [-Werror=undef]
     # elif 199901 <= __STDC_VERSION__
                      ^
    input.c:256:18: error: "__STDC_VERSION__" is not defined [-Werror=undef]
     # elif 199901 <= __STDC_VERSION__
                      ^

* data/skeletons/yacc.c: Check that __STDC_VERSION__ is defined before
using it.
