I managed to:
- check out sources,
- configure and build them, and
- check and install the build.

My next step was to see where to add a dg-error testcase, but I didn't 
find a place.

Attached is a patch that creates a standalone test-case testing dg-error 
using a dummy tool.

Output is as follows:
...
Test Run By vries on Wed May 24 14:46:00 2017
Native configuration is x86_64-unknown-linux-gnu

                === dummy tests ===

Schedule of variations:
    unix

Running target unix
Using /usr/share/dejagnu/baseboards/unix.exp as board description file 
for target.
Using /usr/share/dejagnu/config/unix.exp as generic interface file for 
target.
Using /home/vries/dejagnu/standalone/testsuite/config/default.exp as 
tool-and-target-specific interface file.
Running /home/vries/dejagnu/standalone/testsuite/dummy.dg/dg.exp ...

                === dummy Summary ===

# of expected passes            2
...

If something like this is good to have in the dejagnu sources, I could 
use some pointers on where and how to integrate this.

Thanks,
