We modify these all the time from .ecm scripts, so there must
be some other problem at work here.
If you modify these values, do you see them if you export the
% ecosconfig export cfg
The file 'cfg' should show the modified values.
Of course, don't forget to rebuild your build tree after making the
changes. Using the CLI
% ecosconfig tree
Until you do this step, only the configuration database changes, not
the actual build. This includes the "include" files used by the sources
to get at the actual values.
