> The page you mentioned expressly say that these errors can be ignored.

It says,

which IIUC means it should ignore such errors on its own -- not stop
with a hard failure, such as with not being able to construct a path
with a correct nesting level to a script, which is there.

Following make by how it changes its current working directory, I get:

make[3]: Entering directory `/home/lavr/build/i686-pc-cygwin/winsup/doc'
builddir=`pwd` \
&& cd ../../../../cygwin-snapshot-20130925-1/winsup/doc \
&& ../../../../cygwin-snapshot-20130925-1/winsup/doc/xidepend ../../../../cygwin-snapshot-20130925-1/winsup/doc/cygwin-ug-net.xml > "${builddir}/Makefile.dep"
/bin/sh: line 2: ../../../../cygwin-snapshot-20130925-1/winsup/doc/xidepend: No such file or directory

$ cd /home/lavr/build/i686-pc-cygwin/winsup/doc

~/build/i686-pc-cygwin/winsup/doc
$ ls -l ../../../../cygwin-snapshot-20130925-1/winsup/doc/xidepend
-rwxr-xr-x 1 lavr Domain Users 874 Jun  4 07:50 ../../../../cygwin-snapshot-20130925-1/winsup/doc/xidepend

~/build/i686-pc-cygwin/winsup/doc
$ cd ../../../../cygwin-snapshot-20130925-1/winsup/doc

~/cygwin-snapshot-20130925-1/winsup/doc
$ ls -l ../../../../cygwin-snapshot-20130925-1/winsup/doc/xidepend
ls: cannot access ../../../../cygwin-snapshot-20130925-1/winsup/doc/xidepend: No such file or directory

So the xidepend location was calculated correctly w.r.t. to the build directory,
but since cwd changed to the source tree (?), it was no longer valid.
