emerge gnash floods the output with -mcpu=' is deprecated. Use `-mtune=' or '-march=' instead. Reproducible: Always Steps to Reproduce: 1.use -march= in /etc/make.conf 2.emerge gnash 3.

(In reply to comment #1) > CXXFLAGS="-O2 -mcpu=i686 -pipe" ;-)
oh, i _have_ to specify CXXFLAGS? otherwise it will be set as CXXFLAGS="-O2 -mcpu=i686 -pipe" so this is a emerge bug?
Reopening ..
Those flags come from gentoo-x86/profiles/default-linux/x86/make.defaults, maybe release would consider making those use -march?
No! They *definitely* shouldn't be -march, but rather -mtune. That being said, all of default-linux will be soon deprecated, so there's not much point in modifying this now. Anyway, the simplest solution is to set CXXFLAGS=${CFLAGS} in make.conf so you never have to worry about this, again.
Marking wontfix per above comments.
