- The stat meters now return an FString instead of sprintfing into a fixed output buffer. - NOASM is now automatically defined when compiling for a non-x86 target. - Some changes have been made to the integral types in doomtype.h: - For consistancy with the other integral types, byte is no longer a synonym for BYTE. - Most uses of BOOL have been change to the standard C++ bool type. Those that weren't were changed to INTBOOL to indicate they may contain values other than 0 or 1 but are still used as a boolean. - Compiler-provided types with explicit bit sizes are now used. In particular, DWORD is no longer a long so it will work with both 64-bit Windows and Linux. - Since some files need to include Windows headers, uint32 is a synonym for the non-Windows version of DWORD. - Removed d_textur.h. The pic_t struct it defined was used nowhere, and that was all it contained. SVN r326 (trunk)
