Here it works, i have tried:

 build -verbose -DCFLAGS=-I/usr/lib/malloc c-delete c-lib

and this created:

 gcc -I/usr/lib/malloc -Wall ...

But what i have seen is that multiple settings in CFLAGS are not 
correctly passed to gcc (they are quoted if passed in build.properties).

I'm a bit stuck in this case as i have no MacOSX at hand.

To summarize:

- The C and C++ code works fine on MacOSX (compiled manually)
- The build process with ant needs currently three workarounds for 
simple compilation
