Subject: [PATCH] 2001-02-15  Rodney Brown  <RodneyBrown@mynd.com>

        * acinclude.m4 (GLIBCPP_CHECK_MATH_DECL_1):
        Include ieeefp.h for fpclass on UnixWare{2,7}.
	* aclocal.m4: Regenerate.
	* configure: Regenerate.
        * mkcheck.in (size_command): Do without GNU-grep when using
        size from binutils.
