 If no directory prefix is given, the files are assumed to be in the

+Files mentioned in @code{LIBOBJS} which need de-ANSI-fication will not
+be automatically handled.  That's because @code{configure} will generate
+an object name like @file{regex.o}, while @code{make} will be looking
+for @file{regex_.o} (when de-ANSI-fying).  Eventually this problem will
+be fixed via @code{autoconf} magic, but for now you must put this code
+into your @file{configure.in}, just before the @code{AC_OUTPUT} call:
+
+@example
+# This is necessary so that .o files in LIBOBJS are also built via
+# the ANSI2KNR-filtering rules.
+LIBOBJS=`echo $LIBOBJS|sed 's/\.o /\$U.o /g;s/\.o$/\$U.o/'`
