	* elf/dl-load.c (open_path): Take extra argument PRELOADED.
	If PRELOADED is nonzero check in case of an SUID application
	whether the shared object has the SUID bit set.
	Fix some other problems with handling shared objects in system
	specific directories.
	(_dl_map_object): Also take extra parameter and pass it to open_path.
	* elf/link.h (_dl_map_object): Correct prototype and comment.
	* elf/rtld.c (dl_main): Call _dl_map_object correctly.
	* elf/dl-open.c (_dl_open): Likewise.
	* elf/dl-deps.c (openaux, _dl_map_object_deps): Likewise.

	* sysdeps/libm-ieee754/s_modfl.c: Handle numbers > 1.0 correctly.

	* math/libm-test.c (modf_test): Add test for 1.5.
