| # This shell script should be invoked as |

| # host The configuration host |
| # host_cpu The configuration host CPU |
| # target_optspace --enable-target-optspace ("yes", "no", "") |
| # GCC should be "yes" if using gcc |
| |

| # gc_cflags Special CFLAGS to use when building |
| |
| gc_cflags="" |

| # We should set -fexceptions if we are using gcc and might be used |
| # inside something like gcj. This is the zeroth approximation: |
