- Fixed GCC 4 warnings in FNodeBuilder::CreateSubsectorsForReal().

- Changed f_finale.cpp/atkstates[] into a static variable, since its
  anonymous type prevents it from being accessed from other files anyway.
- Fixed: The behavior of the eventtail advancement in d_net.cpp/CheckAbort()
  was compiler-dependant.
- Fixed warnings GCC 4 threw up while compiling re2c and lemon.
- Removed __cdecl from makewad.c again. This is already defined as a builtin
  for MinGW, and redefining it produces a warning. (Why is main explicitly
  declared __cdecl anyway?)
- Fixed building ccdv-win32 with GCC 4. GCC 4 creates a memcpy call, which
  won't work because it doesn't get linked with the standard C library.
