Thanks for pointing me to these instructions. However, it may require of me
more time that I am can afford. I do not understand some of the
instructions. One of the bullets says:

"cd into libs/config/test/all and run bjam *MACRONAME compiler-list*, where

This "compiler-list", I obviously want the macro to work for all possible
compilers supported by Boost (and perhaps more), but locally, I can only
test it on one. In order to define macro correctly, I would have to use
Boost's testing facility, but they are only run on develop and master
branches which I cannot commit to. Without having tested my macros on all
compilers, I am not sure if my pull request would be a decent one. IOW, I
have a chicken and egg problem here, which I do not know how to solve.

any help would be much appreciated.
