+ linkat: Work around AIX 7.1 bug.
+ * m4/linkat.m4 (gl_FUNC_LINKAT): Require AC_CANONICAL_HOST. Test
+ whether linkat handles trailing slash correctly. If not, replace linkat
+ and define LINKAT_TRAILING_SLASH_BUG.
+ * lib/linkat.c (rpl_linkat): If LINKAT_TRAILING_SLASH_BUG is defined,
+ check whether (fd1,file1) points to a directory if file1 or file2 ends
+ in a slash. Code taken from lib/link.c.
+ * doc/posix-functions/linkat.texi: Mention trailing slash bug.

+ Correctly determine whether pow is available in libc on AIX 7 with xlc.
+ * m4/mathfunc.m4 (gl_MATHFUNC): Actually use the 'funcptr' variable.
+ This disables an xlc optimization that was causing wrong test results.
