premake: document extra_params ogl: remove EXT_ symbols, use glext instead adts: move cache into separate file (also remove old cache impl) move SDL files in sysdep/win to libraries/SDL ScopeTimerAccrue: change #ifdef spaghetti into templated policy class app_hooks, define VOID_FUNC to FUNC(.., (void) ) look at stalk walk code; any reason not to work on Win64? replace ERR_TEX_CODEC_CANNOT_HANDLE with INFO_* - not an error. also ERR_SYM_SUPPRESS_OUTPUT ERR_SYM_SINGLE_SYMBOL_LIMIT wdbg_sym: only import RtlCaptureContext once (not every walk_stack) add sys_last_error (!GetLastError on win32); converts to text in display_error, also show sys_last_error and errno app_hooks: move i18n impl out (belongs in pyrogenesis) fixes to string_s test. refs #124 This was SVN commit r4020.
