qzdoom/src/sound/altsound.h
Randy Heit cb18719d05 - Fixed: The new sound pausing on menu open interrupted Strife conversations.
- Did some very preliminary support for x64 compiling.
- Now I see why makewad is using the __fastcall calling convention by default:
  Because the release zlib is built with it as well.
- Fixed: Conversion from 'const char *' to 'char *' in DEM_SAVEGAME case in
  Net_DoCommand().
- Updated the project files for Visual C++ 2005.
