platforms this needs special treatment:
- RISC OS:
Norcroft C treats char = unsigned char as legal assignment
but char* = unsigned char* as illegal assignment
and the same applies to the signed variants as well. Thus we use
char which is anyway unsigned.
- Windows:
Windows typedefs byte in the RPC headers but we need to avoid a
warning about a double definition.
