[Myrinet] GM - preprocessing

Hi,

The code for the mcp for GM contains a lot of prepossessing directives. Is
there any way to get the source code after those directives have been
processed. I know cpp does this, but i am not sure what things need to be
changed in the makefile. Has anyone tried to do this...?

any help is appreciated, TIA
anand
