1. _When_ was this?
2. _Who_ was encouraging this?
. . . because it sure as hell hasn't ever been in the official
documentation.
Last year I wrote the optimization guide[1] in part to stem the flood of
bad advice on the unofficial gentoo-wiki, and by uninformed users on the
forums.
There hasn't been any official documentation telling users to do foolish
things with their CFLAGS or LDFLAGS.
