* acgeneral.m4 (AC_CHECK_MEMBER): It is not smart to define ac_Foo, and use AC_Foo. Got rid of AC_Member_Aggregate and AC_Member_Member which were complicating more than simplifying. (AC_CHECK_DECLS): Use m4 lists. (AC_CHECK_TYPES): A comma was missing. * autoheader.m4: (AC_CHECK_DECLS): Use m4 lists. * doc/autoconf.texi (Generic Declarations): AC_CHECK_DELCS uses m4 lists. * tests/semantics.m4: New file. Collection of semantical tests: verify that the tests are positive and negative when appropriate. Test AC_CHECK_MEMBERS, AC_CHECK_DECLS and AC_CHECK_TYPES.
