        * COPYING.NEWLIB: Add Altera Corporation copyright.
Reverted XInclude in cygwin-api.in.xml from an XInclude to a DOCTOOL
include.  You can't mix the two fragment inclusion mechanisms within
a single document because of the way it interacts with autoconf "build
in separate tree" mechanism.  Either work separately, but they fail when
you try to use them together due to the way doctool chooses output
directories for its generated files.
