      Pass --enable-target-optspace to crossgcc's configure.

      This will compile crossgcc's libs with -Os.

    help

      If you get the missing symbol "__cxa_atexit" when building C++ programs,

      you might want to try disabling this option.

    default n

    help

      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:

    bool

    prompt "Let configure decide"

    help

      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

    bool

    prompt "Force using sjlj"

    help

      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.
