Question:
The build toolchain (abld etc) seems to have a limit with regards to the number of folders down from root where items can be located. What is the limit and how is it defined ?

Answer:
The full filename/path from the root of the drive cannot exceed 256 bytes. There is no limit on levels of nesting as such, except in the way that nesting contributes to the overall path length.

The 256 byte limit originates in the Cygwin DLL which is used by our GCC compiler.
