I also encountered many strange things when compiling parts of FreeBSD with this change!
For example, ssh's smult_curve25519_ref.c gets miscompiled somehow, and then ssh signature checking fails. Another example, subversion's SQLite support gets completely broken. Probably there were more miscompilations lurking around.
I'm not sure if it is easy to come up with simple test case. But please make sure this commit gets more thought before reapplying it again. :)
