I get this error "lcc preprocessor error: IRLS.c:16 Macro redefinition of NULL" when I try to compile a C code for matlabusage using mex command

I get the error "lcc preprocessor error: IRLS.c:16 Macro redefinition of NULL" when i run "mex file.c" in matlab.

The code file.c has the following line "#define NULL 0". Is there a simple way to fix this?

Thanks
