The arrival of pacman 6.1 and related changes show some impact on Firejails build output when using --enable-analyzer. I'm seeing a large number of repeated output like the below:

[...]
<command-line>: warning: "_FORTIFY_SOURCE" redefined
<command-line>: note: this is the location of the previous definition
[...]

Nothing breaks, so this isn't urgent IMO, more of a FYI.

Details that might help grokking this:

$ pacman -Q gcc pacman
gcc 13.2.1-5
pacman 6.1.0-3

[pacman 6.0] [Core]
