Log message:
        * src/main.c (stackovf_handler): Document the problems in our
        overflow handler.
        * src/stackovf.c: Forward port changes in branch to use POSIX
        sa_sigaction when available.
        (process_sigsegv): Avoid buffer overrun when error string is
        translated, although the fact that we translate in a signal
        handler is still a bug.
        * ltdl/m4/stackovf.m4 (M4_SYS_STACKOVF): Forward port changes
        from branch to modernize checks.
