Makefile.in ($(srcdir)/c-parse.y: c-parse.in): Enclose the whole message in quotes.

        * Makefile.in ($(srcdir)/c-parse.y: c-parse.in): Enclose the whole
        message in quotes. Otherwise, IBM's make program treats the '#' as the
        start of a comment and ignores the remainder of the line.

        * c-lex.c (yylex): Change for EBCDIC, lower case characters preceed
        upper case.
        * cccp.c (initialize_char_syntax): Allow for holes in EBCDIC.
        * cexp.y (initialize_random_junk): Likewise.
        * cppfiles.c (find_include_file): Cast alloca return value.
        * cppinit.c (initialize_standard_includes): Likewise.
        * cpplib.c (cpp_define, cpp_undef): Likewise.
        * defaults.h (ASM_OUTPUT_ASCII): Use ISPRINT.
        * final.c (output_asm_insn): Allow for holes in EBCDIC.
        * fold-const.c (CHARMASK): New.
        (real_hex_to_f): Use it.
        * real.c (CHARMASK): New.
        (etoasc, asctoeg): Use it.
        (asctoeg): EBCDIC lower case characters preceed upper case.
