Well I'm not touching WARN_CFLAGS and effectively only adding -fanalyzer above.
The WERROR_CFLAGS= is to keep going to get all warnings for the build.
Note -Wanalyzer... flags are ineffective without -fanalyzer.
Also -Wanalyzer-too-complex (now auto enabled by gnulib) is currently quite 
problematic with -fanalyzer.
