This is better, but still wrong according to the gnu makefile
standards; I've included the relevant fragment below. Similarly,
aclocal.m4 macros are not supposed to stuff required flags into the
CFLAGS environment variable.

   If there are C compiler options that *must* be used for proper
compilation of certain files, do not include them in `CFLAGS'.  Users
expect to be able to specify `CFLAGS' freely themselves.  Instead,
arrange to pass the necessary options to the C compiler independently
of `CFLAGS', by writing them explicitly in the compilation commands or
by defining an implicit rule, like this:
     CFLAGS = -g
     ALL_CFLAGS = -I. $(CFLAGS)
     .c.o:
             $(CC) -c $(CPPFLAGS) $(ALL_CFLAGS) $<
   Do include the `-g' option in `CFLAGS', because that is not
*required* for proper compilation.  You can consider it a default that
is only recommended.  If the package is set up so that it is compiled
with GCC by default, then you might as well include `-O' in the default
value of `CFLAGS' as well.
