But rather to check various stuff needed for C-programming . Like walking the list of %INCLUDE / %C_INCLUDE_PATH dirs to figure out what headers are where. So I'd just as well add an option to check for Python paths too (if Python is installed that is). > What are your real constraints? Are you just playing code-golf? That too. --gv
