Description of Problem:

Suppose two packages both try to supply a header file <machine/types.h>
The current makefile generator does not detect this, and it is not obvious
which header file will actually get used. The result is strange build failures.

Version-Release number of selected component (if applicable):

CVS

How Reproducible:

Probably depends in part on timestamps in the source tree.

Steps to Reproduce:
1. create a header <machine/types.h> in both CYGPKG_NET and
CYGPKG_NET_OPENBSD_STACK, where the former is blank
2. try to build a configuration using the net template
3. if the wrong header gets copied across, the build will fail with strange errors.

Actual Results:

Strange build failures.

Expected Results:

An error message from "ecosconfig tree" saying that the two packages conflict.
