/* We use byte as an abbreviation for unsigned char. On some

|
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.
