    * setjmp.S on i386
    * getenv on i386
    * sys/stat.h -malign-double fix
    * update fcntl.h for MIPS to 2.6.13 version
    * jmp_buf is 40*8 instead of 58*8 on ppc64.
    * This patch fixes the section of the TOC entries on ppc64
    * libstdc++ updates for gcc 4
    * remove cstddef and cwchar (no longer needed)
    * int -> ssize_t for read and write
