Alan, this is a good point and highlights a weakness in the current positioning
of the bsp includes. In this context it would seem to be a mistake to have the
includes under 'bsps' because it leads to a duplicated name of some type at the
top level. A 'bsps/include' directory would make the BSPs consistent with
'cpukit/include' plus it is a sensible path.

I think a tree plan needs to be made before we move any more code about to avoid
moving twice. As a starting point for a discussion here is a list:

- Removing 'c' moving all contents to other parts of the tree
  - bsps/. => bsps/include
  - c/src/lib/libbsp/. => bsps/
  - c/src/ada => ada
  - c/src/support/verison.c => cpukit/sapi/version-string.c
  - c/src/bsp.pc.in => bsps/
  - c/src/libchip => devices (not sure about this)
- Rename cpukit because *kit means nothing
  - cpukit => kernel
