| dnl This configure script is complicated, because GRUB needs to deal |
| dnl with three potentially different types: |
| dnl |
| dnl build -- the environment for building GRUB |
| dnl host -- the environment for running utilities |
| dnl target -- the environment for running GRUB |
| dnl |
| dnl In addition, GRUB needs to deal with a platform specification |
| dnl which specifies the system running GRUB, such as firmware. |
| dnl This is necessary because the target type in autoconf does not |
| dnl describe such a system very well. |
| dnl |
| dnl The current strategy is to use variables with no prefix (such as |
| dnl CC, CFLAGS, etc.) for the host type as well as the build type, |
| dnl because GRUB does not need to use those variables for the build |
| dnl type, so there is no conflict. Variables with the prefix "TARGET_" |
| dnl (such as TARGET_CC, TARGET_CFLAGS, etc.) are used for the target |
| dnl type. |
