It seems that xidepend doesn't work correctly if we are ./configure'd using a

grep: ../../../../src/winsup/doc/cygwin-ug-net.xml: No such file or directory
grep: ../../../../src/winsup/doc/cygwin-api.xml: No such file or directory
Although it might be better to fix this by making xidepend use pathnames, rather
than ignoring them and assuming everything is in the current directory...
