- debug: add provision for naming threads. allows adding current thread name to log messages and displays their names in the debugger. - replaced various if(err < 0) complain() sequences with new variants of CHECK_ERR (see lib.h) - fixes to mmgr/VC debug alloc enable code - improved h_mgr error reporting (now complains when h_free fails) - US -> UK english (partial) - fix tex_load double-free bug - move win32 mouse cursor code into sysdep - error dialog is now topmost to make sure it's visible (was a problem) - handle WM_QUIT before displaying error dialog (makes sure it's shown) also as in previous 3 revisions. This was SVN commit r2588.
