	* configure.ac: Add -fno-omit-frame-pointer after -Os in default
	  cflags, just to be sure.
	  Fedora's readline library does not itself link to termcap, hence
	  we must pass the result of termcap tests in via OTHER-LIBRARIES
	  argument, otherwise the test of main in readline will fail due to
	  missing termcap systems. On systems like Debian, -ltermcap
	  is not needed for the readline test, because libreadline already
	  links to it.
