- remove headers always included from PCH - nommgr.h is only included ifdef REDEFINED_NEW (allows leaving out the mmgr stuff) - in lib/*.cpp, moved the corresponding include file to right behind the PCH (catches headers that aren't compilable by themselves) - byte_order no longer depends on SDL - add debug_level (another means of filtering debug output; needed for thesis) - split posix stuff up into subdirs (lib/posix and sysdep/win/wposix). makes including only some of the modules (e.g. sockets, time) much easier. This was SVN commit r4728.
