+       math, unistd: avoid redundant includes
+       * lib/math.in.h (isnan): No need to re-include <math.h>.
+       * lib/unistd.in.h (getcwd): Likewise, for <stdlib.h>.
+
        getsubopt: work around cygwin bug
        * lib/stdlib.in.h (includes): Move unistd inclusion sooner, to
        avoid conflicting with system getsubopt.
