- 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. SVN r135 (trunk)

/* You need Bison (or maybe Yacc) to rebuild the .c file from this grammar.

|
* Or you could rewrite it to use Lemon, since the ZDoom source comes with Lemon.
|
|
* Since I have Bison, and the existing code works fine, there's no motivation
