+Running the following:
+
+    make LDFLAGS+=-nostdlib 2>&1 | sed -ne 's/.*undefined reference to `\(.*\)..*/\1/gp' | sort | uniq
+
+reveals the list of all external (i.e. libc) things that BusyBox depends on.
+It would be a very nice thing to reduce this list to an absolute minimum, and
+then create a microLibc to provide these functions.  There is no good reason
+for GNU libc to be so big.  I'm sure it can be a lot better.

 Compile with debugging on, run 'nm --size-sort ./busybox'
 and then start with the biggest things and make them smaller...
