patch to pacify GCC when flex 2.5.31 is used

[Paul Eggert]

I installed this awful hack.  Suggestions for improvement are welcome.

2005-07-20  Paul Eggert  <address@hidden>

        * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
        (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
        (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
        Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
        is used.
        * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
        (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
        (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
        Likewise.
