include files for cgxCADTools

[Joshua Root]

A lot of them aren't even standard headers; I believe the ones under 
bits/ are glibc implementation details. I would suspect this part of the 
Makefile was not hand-written but generated with one of the compiler's 
-M options. To work correctly in that case, it would need to be 
regenerated for each new system the software is built on.
