That doesn't appear to work here. gcc -Wno-error=pedantic -Wpedantic does work, but causes an (easily-fixed) compilation error (I didn't know -W flags could do that!) in seccomp-filter.c, and tons of warnings about things like statement expressions:

igc.c:1917:25: warning: imaginary constants are a GCC extension
 1917 |   ssize_t count_total = 0i;
      |                         ^~

I'm using the 20240614 version of gcc 13.3.1.
