KYRA: does not compile in MSVC71
|Reported by:||SF/quietust||Owned by:||athrxx|
"engines/kyra/sound_towns.cpp" fails to compile due to M_PI not being defined. This appears to be due to sound_towns.cpp #defining _USE_MATH_DEFINES and then explicitly including <math.h> after all of the standard includes, even though "common/scummsys.h" (which is included by "common/system.h") already includes <math.h> on its own, causing further inclusions to have no effect.
Visual Studio 9.0 (2008) seems to have reorganized <math.h> by adding a separate include-once block around the math defines, so it compiles in that version without problems.
