+2001-09-15 Paul Eggert <eggert@twinsun.com>
+
+ Fix bug reported by Paul Townsend on AIX 4.3.3.0 with
+ CFLAGS=-O4 or CFLAGS=-O5. In that case, the linker has a
+ relaxed view of fatal errors, and AC_CHECK_LIB causes it to
+ include libraries even when they don't exist.
+
+ * acheaders.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS, not
+ AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
+ need it.
+
+ * acspecific.m4 (AC_ISC_POSIX): Replace the old, crufty
+ version with the version used by fileutils 4.1, except use
+ AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use
+ -lcposix if we don't need it.
