The gcc driver does some expansion of the arg and -MD option gets down 
to the processor as "-MD <filename>.d". Since you're passing -MD 
directly to the preprocessor there is no expansion and the preprocessor 
is treating the following option as the argument. You could the 
expansion if you're compiling a single source file and name the dep file 
yourself. i.e. -Wp,-MD,c1.d but this won't work if you're compiling 
multiple source files per invocation.
