In x86_64-unknown-linux-gnu/libjava/classpath/lib, there are
# find -name *.list | xargs grep gcc/libjava/java/net/URL.java
./lists/java-net.list:/net/gnu-13/export/gnu/src/gcc/gcc/libjava/java/net/URL.java
./lists/gnu-src-gcc.list:/net/gnu-13/export/gnu/src/gcc/gcc/libjava/java/net/URL.java
classpath/lib/Makefile.gcj has
%.stamp: %.list
$(GCJF) -MD -MF ${@:.stamp=.deps} -MT $@ -MP @$<
echo timestamp > $@
That means lists/java-net.stamp and lists/gnu-src-gcc.stamp may be
built at the same time, which lead to
