Well, yes, Autoconf had to go the compromise and detect *these* flags
also when they were in the environment.  But it only does so for a few
common variables.  You have to declare a variable as `precious' if you,
the developer, want another variable recorded; see
  info Autoconf 'Setting Output Variables'

By the way, if you use AC_CONFIG_SUBDIRS, you may end up with a "parent configure" script that does not treat CFLAGS as a precious variable. But the "child configure" may need it.

If you type:
./config.status --version
you will not see any 'CFLAGS'. But if you:
./child/config.status --version
then you will.
