You need to look around at multiple places in the documentation for that combination. The first part (-Wp) is described here (near the top): http://gcc.gnu.org/onlinedocs/gcc-4.4.0/gcc/Preprocessor-Options.html#Preprocessor-Options Basically, anything that is -Wp,<something> means that the "<something>" is passed exactly as is to cpp. The -MD option to the preprocessor is described in a later section on the same page. The summary is that this command line is generating a dependency tree for the file and saving it on disk for use by make.
