Re: 4.2.0-pre-2

[Wayne Davison <wayned@xxxxxxxxxxxxxxxxxxxxx>]

I noticed that someone removed the stamp-h idiom from the Makefile
recently.  This means that we no longer handle the case where configure
gets rerun (generating a new config.status) but the config.h file didn't
change (so it's timestamp doesn't update).  When this happens the
config.h rules will get rerun every time you type "make".  The attached
patch fixes this.
