Description genBTC 2023-06-24 14:12:13 UTC 
When using gentoo-hardened with the new  fortify-source-3.patch  built into gcc-12.2.1_p20230428-r1 ,
net-vpn/i2pd package with the i2p-hardening USE flag enabled:
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:
 @ CMakeLists.txt line 134 : add_definitions("-D_FORTIFY_SOURCE=2")
 @  & build.ninja (generated command)
that flag should be stripped so _F_S=3 can take effect from the gcc spec profile without conflict.
