Hmmm, sorry to pipe in so late, but I'm confused about this.  In the
awklib/Makefile.am patch, the stamp-eg file is now being created in $(srcdir).
But I thought the idea when using VPATH was that the source tree should not be
touched (i.e. it should be read-only).  So why are we creating the "eg"
directory inside $(srcdir) instead of inside the build directory?  And what
happens if two different builds on two different architectures (with different
build directories but the same srcdir) are occurring at the same time?
Couldn't this confuse make and leave a garbled result?
