Warning fixes:

        * mips/iris6.h (TARGET_DEFAULT): Parenthesize macro definition.
        * mips/mips.c: Include stdlib.h and unistd.h.
        (mips_asm_file_end): Add braces around empty body in an if-statement.
        (function_prologue): Wrap variable `fnname' in
        !FUNCTION_NAME_ALREADY_DECLARED.  Correct format specifier in fprintf.
        (mips_select_rtx_section, mips_select_section): Declare as void.
        * mips/mips.h: Add prototypes for extern functions in mips.c.
        (FUNCTION_ARG_REGNO_P): Add parentheses around && within ||.
        (ENCODE_SECTION_INFO): Add braces around empty body in an
        if-statement.
        * mips/mips.md (movdi): Add parentheses around && within ||.
        (movsf, movdf): Likewise.
        (branch_zero, branch_zero_di): Add default case in
        enumeration switch.
