FYI: I am currently struggling a bit with Eclipse's linked folders under
Eclipse 3.6 + CDT 7.0.2.
This has the consequence, that I can not add a link to
PROJECT_SOURCE_DIR and PROJECT_BINARY_DIR
without causing troubles with the CDT indexer. I'd really like to have a
the global project similar to the project your generator creates.
With Eclipse 3.7 and CDT 8 these problems seem to be resolved.
So that feature is currently deactivated and I will make it switchable
for edge-affine eclipse users.
When the next version is released officially it's gonna be the default
behavior.

Bye,
Oliver
