I missed a few episodes of this saga, but here's an illustration that
hopefully will drive the point home.
Look at this tiny project, and see how it compiles fine when called from
P:\org_apache\antx\acme, or P:\org_apache\antx\acme\build, or finally
P:\org_apache\antx. In all cases, the src and classes properties point to
the valid directories (P:\org_apache\antx\acme\src and
P:\org_apache\antx\acme\classes). If the paths stored in the src / classes
properties were relative to the current directory (like in a Windows cmd
session, or *nix shell session), 2 of the 3 build commands should have
failed. The point is that these two paths are relative to the project's
'basedir' attribute, itself being relative to the actual location in the
filesystem of the build.xml file ant parses.
When you start ant, it knows where it is (the current dir).
You passed it the path, relative or absolute, to the build.xml file, so it
knows where that one is (absolutely).
It can thus deduce the absolute path corresponding to the project basedir,
in this case P:\org_apache\antx\acme (since basedir=".." of build file
P:\org_apache\antx\acme\build\build.xml).
Now I'm gonna read Diane's answer ;-) --DD

I never meant for this to drag out for so long, but let me try
one more increment. Maybe we can identity where our understandings
of the meaning of "relative" diverge. (It might be in Windows vs.
in Ant.)
on and on it goes...
