2002-11-24 Roland McGrath <roland@redhat.com>
+ * sysdeps/posix/readv.c: Include <errno.h>, use __set_errno macro.
+ * sysdeps/posix/writev.c: Likewise.
+ From Momchil Velikov <velco@fadata.bg>.
+
+ * elf/dl-error.c [! _LIBC_REENTRANT]: Use a static variable instead of
+ calling *GL(dl_error_catch_tsd) for a thread-local location.
+ * elf/rtld.c (startup_error_tsd): Conditionalize on [_LIBC_REENTRANT].
+ (dl_main): Same for GL(dl_error_catch_tsd) initialization.
+ * elf/dl-tsd.c: Conditionalize contents on [_LIBC_REENTRANT].
+
+ * libio/iofflush.c: Add libc_hidden_def.
+ * libio/iofwrite.c: Likewise.
+ * sysdeps/generic/sigtimedwait.c: Likewise.
+ * sysdeps/generic/sigwaitinfo.c: Likewise.
+ * sysdeps/posix/sigwait.c: Likewise.
+ Reported by Momchil Velikov <velco@fadata.bg>.
+
+ * inet/inet_lnaof.c (inet_lnaof): Change return type to in_addr_t
+ to match <arpa/inet.h> declaration.
+ * inet/inet_netof.c (inet_netof): Likewise.
+ * inet/inet_mkadr.c (inet_makeaddr): Likewise for argument types.
+ Reported by Momchil Velikov <velco@fadata.bg>.
+
* configure.in: Skip AUTOCONF check under --without-cvs.
* configure: Regenerated.
