reverting most of the c_strcasecmp change

[Paul Eggert]

I installed the following now that gnulib supports strcasecmp better.

2007-02-07  Paul Eggert  <address@hidden>

        Undo most of the 2007-02-03 change, switching to the strcase module
        now that gnulib strcase has been fixed.
        * bootstrap.conf (gnulib_modules): Remove c-strcase.  Add strcase.
        * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
        c-strcasecomp.c, c-strncasecmp.c.  Add strcasecmp.c, strncasecmp.c
        * m4/.cvsignore: Add strcase.m4.
        * src/getargs.c: Revert 2007-02-03 change, as follows.
        Don't include c-strcase.h.
        (language_argmatch): Use strcasecmp rather than c_strcasecmp.
        strcasecmp has "unspecified behavior" outside the POSIX locale,
        but it works fine in practice if at least one argument is ASCII,
        as is the case in Bison.
