	* iconv/gconv_conf.c (__gconv_read_conf): Use __realpath not realpath.
	* iconv/gconv_db.c: Use __ protected regex functions.
	* iconv/gconv_simple.c: Use __mbsinit not mbsinit.
	* posix/getopt_init.c: Use __getpid not getpid.
	* posix/regex.c: Rename all global functions to start with __ and
	make old names weak aliases.
	* posix/regex.h: Adopt prototypes for this.
	* stdlib/canonicalize.c: Define __realpath, make canonicalize_file_name
	a weak alias and use __getcwd instead of getcwd.
	* stdlib/stdlib.h: Declare __realpath and __canonicalize_file_name.
	* stdlib/strtod.c: Use __btowc instead of btowc.
	* stdlib/strtol.c: Likewise.
	* sysdeps/libm-ieee754/s_matherr.c: Weaken definition of matherr.
	* sysdeps/unix/sysv/linux/errlist.c: Make sure definitions of sys_nerr
	and sys_errlist are weak.
	* wcsmbs/btowc.c: Define function as __btowc and make btowc weak alias.
	* wcsmbs/mbrtowc.c: Use __mbsinit not mbsinit.
	* wcsmbs/mbsnrtowcs.c: Likewise.
	* wcsmbs/mbsrtowcs.c: Likewise.
	* wcsmbs/wcsnrtombs.c: Likewise.
	* wcsmbs/wcsrtombs.c: Likewise.
	* wcsmbs/mbsinit.c: Define function as __mbsinit and make mbsinit
	weak alias.
	* wcsmbs/wchar.h: Declare __btowc and __mbsinit.
