| # configure.host | |
| # This shell script handles all host based configuration for the garbage | |

| # needing to rerun autoconf. | |
| # This shell script should be invoked as | |
| # . configure.host | |
| # If it encounters an error, it will exit with a message. | |
| # It uses the following shell variables: | |
| # host The configuration host | |
| # host_cpu The configuration host CPU | |
| # target_optspace --enable-target-optspace ("yes", "no", "") | |
| # GCC should be "yes" if using gcc | |
| # It sets the following shell variables: | |
| # 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: | |
