blah, it's because i misused the AC_REQUIRE helper.  it not only makes sure 
the func is available, but then also calls it.  i don't know of a way to get 
the desired behavior (an m4 error when the macro isn't available) other than 

so the options are:
 - have AX_APPEND_FLAG do nothing when $1 is not set
 - revert my change
