Bug Fixes in Development Tools
Make relative include entries relative to their own rc-file.
As opposed to making them relative to script location, original rc-file,
initial cwd, or similar. This allows for whole directory trees to be
moved around if need be as well as long as the internal links remain
I've tested this on a sample here and also on the provided test case
with the bug and it seems to work well although I have not had time to
run through a whole build, merely the --pretend sequence.
