Warning fixes:

        * argv.c (buildargv): Cast the result of alloca in assignment.
        * choose-temp.c: Include stdlib.h.
        * cplus-dem.c (demangle_arm_pt): Remove unused prototype.
        (snarf_numeric_literal): Constify first parameter.
        (code_for_qualifier): Avoid a gcc extension, make the parameter an
        int, not a char.
        (demangle_qualifier): Likewise.
        (demangle_signature): Cast the argument of a ctype function to
        unsigned char.
        (arm_pt): Add parens around assignment used as truth value.
        (demangle_arm_hp_template): Constify variable `args'.
        (do_hpacc_template_const_value): Cast the argument of a ctype
        function to unsigned char.
        (do_hpacc_template_literal): Remove unused variable `i'.
        (snarf_numeric_literal): Constify parameter `args'.
        Cast the argument of a ctype function to unsigned char.
        * floatformat.c (floatformat_to_double): Add explicit braces to
        avoid ambiguous `else'.
        * fnmatch.c (fnmatch): Change type of variables `c', `c1',
        `cstart' and `cend' to unsigned char.  Cast the argument of macro
        `FOLD', which uses ctype functions, to unsigned char.
        * objalloc.c (free): Add prototype.
