unsigned char vs TQ3Uns8

[Daniele C. <dca...@in...>]

Is there a good justify for use in quesa's release 1.8 unsigned char 
rather than TQ3Uns8?
When I compile rayshade there are a lot of error for this.
I repleaced unsigned char with TQ3Uns8 for compile it
In file RS_Texture.cpp into function rs_TextureConvertMemory there is 
a type error  "not srcBigEndian"
