CCS 5.5 Headless build questions and issues

Hello all,

I have been using the CDT headless build on CCS5.2 and earlier, but now with 5.5 the clean process fails (it fails to issue the DEL /F command part of the clean, and tries to execute all the object files.  I'm not sure why this is happening, but to get support on this, I figured I first had to switch to using the CCS style of the headless builds and it all seems to be working, except...

How do I add a specific compile flag to each file being compiled? 

using the CDT eclipse, I just had to add the usual compile "-D <MY_COMPILE_FLAG>" to the command.  I tried using the ccs.args <file.txt> where file.txt contained both quoted and unquoted "-D <MY_COMPILE_FLAG>" but that did not work...

Any advise on how to get a compile time flag added to the headless build...  I prefer not to have to create another target (I have DEBUG, and RELEASE, and prefer not to have a special target for this flag)

Also, is there a way to do a clean headless build?  or do I have to issue the commands separately? (command with "-ccs.buildType clean", followed by another command with "-ccs.buildType full")

Thanks,
