OK, I see now that this is an FAQ issue being addressed (Thanks! ;-)
but since you asked.  In order, seen after running top-level gmake:

top-level and gcc are not reconfigured.
libiberty is reconfigured, nothing else rebuilt due to this reconf.
libstdc++ is reconfigured, nothing else rebuilt due to this reconf.
libf2c is reconfigured, *everything* is rebuilt due to this reconf.
  (everything being rebuilt after reconf is not new; reconf every gmake is.)
libffi is reconfigured, nothing else rebuilt due to this reconf.
boehm-gc is reconfigured, nothing else rebuilt due to this reconf.
zlib is reconfigured, nothing else rebuilt due to this reconf.
libjava is reconfigured, all C++ code rebuilt; Java code not rebuilt.

For the record, I don't mind waiting the few seconds for the extra
reconfigurations; it is the secondary effects that are quite painful
IMHO.

Regards,
Loren
