Description genBTC 2023-01-09 08:53:50 UTC
When using gentoo-hardened with the new  fortify-source-3.patch  built into Gcc-12.2.1_p20221231 ,
net-fs/cifs-utils package results in a warning about a definition redefined collision.

<command-line>: warning: "_FORTIFY_SOURCE" redefined
<built-in>: note: this is the location of the previous definition

Meaning the package has _F_S=2 hardcoded internally:
 @ / / Makefile  (all)
that flag should be stripped so _F_S=3 can take effect without conflict.

Reproducible: Always
