      Pass --enable-target-optspace to crossgcc's configure.
      
      This will compile crossgcc's libs with -Os.

      If you get the missing symbol "__cxa_atexit" when building C++ programs,
      you might want to try disabling this option.

      Say 'y' here to not use Pre-Compiled Headers in the resulting toolchain.
      at the expense of speed when compiling C++ code.
      
      For some configurations (most notably canadian?), PCH are broken, and
      need to be disabled. Please see:

      Let configure decide if setjmp/longjmp should be used to handle
      exceptions.
      
      Choose that if you trust configure to detect the correct settings.
      This is the default choice.

config CC_SJLJ_EXCEPTIONS_USE

      Do use setjmp/longjmp for exceptions.
      This is gcc's --enable-sjlj-exceptions configure switch.
      
      Choose that if you want to use setjmp/longjmp to handle exceptions.

config CC_SJLJ_EXCEPTIONS_DONT_USE
    bool
    prompt "Force not using sjlj"
    help
      Do not use setjmp/longjmp for exceptions.
      This is gcc's --disable-sjlj-exceptions configure switch.
      
      Choose that if you want to not use setjmp/longjmp to handle exceptions.
