Hmm I had overlooked ARGN in macros, I kept massaging ARGV.  Also I 
didn't think about writing 3 different ADD_CUSTOM_COMMANDs as at one 
point I was thinking about all the extra compiler options, and I was 
using variable arguments for those.  But I only have 3 different sets of 
compiler options that I use frequently, they could be constantized.  Yes 
I think your solution is an improvement over what I did.
