You have:

checking if x86_64-pc-linux-gnu-gcc -std=gnu99 supports flag -fdiagnostics-color=auto in envvar CFLAGS... yes

and then later:

x86_64-pc-linux-gnu-gcc: error: unrecognized command line option '-fdiagnostics-color=auto'

With the same GCC version I get:

checking if x86_64-pc-linux-gnu-gcc -std=gnu99 supports flag -fdiagnostics-color=auto in envvar CFLAGS... no

and then it compiles fine.

Is there any workaround for this? Or maybe what the cause for the problem is to solve it?

Omg.... Not ccache again...

efialtis nikhatzi # FEATURES="-ccache" emerge kmod
Calculating dependencies... done!
>>> Verifying ebuild manifests
>>> Emerging (1 of 1) sys-apps/kmod-19::gentoo
>>> Installing (1 of 1) sys-apps/kmod-19::gentoo

Without ccache, it compiles fine...

Closing on behalf of ssuominen: "ccache in play, user needs to clear his cache for ccache"
