+# Unfortunately, the 'compare' process will fail (on debugging information)

+# So in the building rule for each stage, we relocate them before and after.
+# The current one is 'gcc', while the previous one is 'prev-gcc'. (The
+# current one must be 'gcc' for now because the scripts in that directory
+# assume it.)
+# At the end of the bootstrap, 'stage3-gcc' must be moved to 'gcc' so that
+# libraries can find it. Ick!
+
+# Bugs: This is almost certainly not parallel-make safe.

+# 'touch' doesn't work right on some platforms.
