Does this mean I should be using a different gcc or CFLAGS?
No. What these warnings mean is that the chromium build system is
passing these options to the compiler:
-Wno-enum-compare-switch -Wno-tautological-unsigned-zero-compare
-Wno-null-pointer-arithmetic -Wno-tautological-constant-compare
but the compiler version installed on your system doesn't support them.
Your own CFLAGS got nothing to do with this. Furthermore, these warnings
are of no interest to you whatsoever, unless you're a chromium developer.
GCC 7.3 and Clang 6.0 do support these options, but if you're using a
version that doesn't, it's of no consequence. Warning options do not
affect code generation.
