        * scripttempl/pe.sc: The Cygwin32 library uses a .data$nocopy
        section to avoid copying certain data on fork.  The linker used to
        include this between __data_start__ and __data_end__, but that
        breaks building the cygwin32 dll.  The fix is to rename the
        section ".data_cygwin_nocopy" and explictly include it after
        __data_end__.
