Hi Martin,

I had a chance to build a test suite combining ede and spp macro 
expansion, but I can't recreate the bug you predict.  I am wondering if 
I'm missing some detail.

For example, I have this in a C file:


#define macro_with_param(ARG) int ARG (int b);

macro_with_param(EDEPART)


and define my project like this:

(ede-cpp-root-project "TMP" :file (expand-file-name "edeconfig.h" root)
			:spp-table '( ("EDEPART" . "C")
				      )
			:spp-files '( "edeconfig.h" ))


Is that too simple?  Is there something more to it?

I pushed the new test suite which is in tests/cedet/semantic/utest-c.el 
with src files in tests/cedet/semantic/testwithede that are used with 
the preprocessor.

Thanks
Eric

Thanks
