* locale/findlocale.c: Add casts to avoid warnings. * locale/localeinfo.h (LIMAGIC): Add cast to avoid warnings. * misc/efgcvt_r.c (fcvt_r): Use ssize_t instead of int and add cast to avoid warnings. * misc/tsearch.c (const_node): New type. (trecurse): Correct casts to avoid warnings. (__twalk): Likewise. * stdlib/tst-limits.c: Add z modifier to formats for WORD_BIT and LONG_BIT. * debug/backtrace-tst.c (compare): Add casts to avoid warnings.
