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