Comments removable from .obj? Optimization of .obj for size by removal of comments possible?

The .obj files produced during compilation of the CUDA SDK sample projects are very large as compared to their actual “useful” code contents. As I see from looking into them with DUMPBIN, they contain a lot of apparently unnecessary information, like my compiler’s search paths at compile time, and so on. Is there any possibility to get rid of all these comments? I wrote a library of complex-number math functions for vectors on CUDA, and I feel its size in bytes could be one tenth of what it is now!
