| 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, variables with prefix "BUILD_" |
| dnl (such as BUILD_CC, BUILD_CFLAGS, etc.) for the build type and variables |
| dnl with the prefix "TARGET_" (such as TARGET_CC, TARGET_CFLAGS, etc.) are |
| dnl used for the target type. See INSTALL for full list of variables. |
