Minimum Version Numbers for Build Tools
Long ago, when this ancient planet was not yet quite so ancient, the Linux kernel refused to support newer versions of the GNU C compiler (GCC). Compiler development proceeded, and Linux would compile only on a specific older version because Linus Torvalds disagreed with some of the new behaviors going into GCC. In other words, it was war.
Today the situation is much different, and the Linux kernel now identifies the minimum version of the tools it requires, rather than the maximum. And today, as Masahiro Yamada pointed out recently, Linux supports GCC version 5.1 and later.
