* sysdeps/posix/tempname.c (__gen_tempname): Change attempts_min
into a macro. Use preprocessor to decide how to initialize attempts [Coverity CID 67]. * io/fts.c (fts_build): Comment out dead code [Coverity CID 68]. * sunrpc/rpc_parse.c (def_union): Comment out dead code [Coverity CID 70]. * locale/programs/linereader.c (lr_token): Remove duplicate handling of EOF [Coverity CID 71]. * locale/programs/ld-numeric.c (numeric_read) [case tok_grouping]: We bail out early if ignore_content is set, so there is no need to check it later again [Coverity CID 72]. * inet/inet6_option.c (inet6_option_find): Check *tptrp for NULL, not tptrp [Coverity CID 73]. * inet/inet6_option.c (inet6_option_next): Check *tptrp for NULL, not tptrp [Coverity CID 74]. * misc/tsearch.c (__tsearch): Don't rotate tree if memory allocation failed [Coverity CID 78].

handling of EOF [Coverity CID 71].

check it later again [Coverity CID 72].
