test test/D/Issues/2944/D_changed_DFLAGS_not_rebuilding.py failing on ubuntu-next

Russel,


Looks like this test turning on the "-d" flag in the second pass is what's
causing the test to fail with gdc 5.3.1

If I change:
if int(change):
    env.Append(DFLAGS = '-d')

to:

if int(change):
    env.Append(DFLAGS = '-Wall)

The test succeeds.
Would this invalidate your test?

What is the "-d" flag supposed to do for gdc?

-Bill
