Description Judge Dredd 2020-12-09 19:58:52 UTC 
www-client/firefox-78.5.0:0/esr78::gentoo  fails to build.

The problem seems to be the -msse4.2 flag, which is a valid flag for gcc,
but for some reason the CFLAGS in the environment contain -msse4_2 flag
which is not a valid gcc flag (mind the underscore)
I suspect that the CPU_FLAGS_X86 in make.conf is not treated properly.

Reproducible: Always

Steps to Reproduce:
1. try to compile www-client/firefox-78.5.0 with x86_64-pc-linux-gnu-9.3.0
2. configure will fail
3.
Actual Results:  
configure will fail

Expected Results:  
compilation and installation

> declare -x CFLAGS="-Ofast -march=native -pipe -funroll-loops -mfpmath=sse -msse4_2 -mavx2 -maes"
Where is this coming from, some package.env file?

ebuild nor firefox certainly wouldn't set a standards-breaking -Ofast, it also doesn't mangle -msse4.2 as far as I can test.

No, "-msse4_2" is coming from *your* environment. Please fix your CFLAGS.

Thank you Thomas, my bad. I didn't notice this.
