All STM32 based demo are now tested with Eclipse Helios.
I have also added the GNU ARM MBS Plugin support. Each workspace contains now two projects. One is configured as a Makefile project (as usual until now). The other project (which name ends with "_mbs") is configured as a managed build project. This means that the Makefile is automatically managed by Eclipse. Add a source file to the project and Eclipse build it. Use the Settings section of the project properties dialog to modify the build option like compiler optimization and so on.
Both projects share the same source file.
