time.h is a set of c functions, and we wanted a class to represent a  
point in time.

...and different widths on different platforms. We use wchar for  
strings and llwchar where we want a fixed width wide character.

do you mean llifstream and llofstream? Windows does not handle  
international character sets correctly with the standard c++ file  
streams. For example, we could not load your user settings if there  
was a non-us-ascii character in the path to your user directory.

We only link to the SDL when building the client in linux. The APR  
library provides a reasonable cross-platform thread representation  
which supports more platforms and is less time consuming to update  
than the boost library. Threads predate the linux client and are in  
many places besides the linux client. If there is some compelling  
reason to specialize LLThread for linux based on SDL the project will  
be considered.
