I'm not sure I understand the question. Generally you should not set BUILD_CC. But Autoconf enables you to set CC manually, in case you want to override the autodetection. Similarily, if you need to override the autodetection in the sub-configure, you can set BUILD_CC. As I said, you usually do not need to override it. > 2.

(binutils, gcc, ...) Some of these projects might be confusing because they may not use the latest versions of autotools. Stepan
