That will be a later step. I forgot to add that I've also changed the cygwin Makefile.in to always generate dependencies for .cc files using the -MD option to gcc. This means that there will be a bunch of .d files in addition to .o files in your build directory. I'm not 100% certain that this is the best way to do this but it was quick and easy and it seems to work without noticeably slowing down the build. Does anyone have any other suggestions for how to do this? I'd love to only generate the .d files when a .c or .cc changes but that's not really easy to do. cgf
