CFLAGS is a user variable and shouldn't be set in either
configure.ac or Makefile.am because that makes it impossible to
override compiler flags at configure or make time.
AC_SUBST the default warning flags into AM_CFLAGS instead, which
is emitted before CFLAGS on the compiler command line.
Do the same thing with a mingw-specific flag as well.
