scummvm/engines/scumm/actor.cpp
Max Horn 0ce2ca4e00 COMMON: Replace MKID_BE by MKTAG 
MKID_BE relied on unspecified behavior of the C++ compiler,
and as such was always a bit unsafe. The new MKTAG macro
is slightly less elegant, but does no longer depend on the
behavior of the compiler.
Inspired by FFmpeg, which has an almost identical macro.
