_DEBUG_x86 MACRO optimization & clarification

[lida2003]

I have searched code, and it exists in two places:

May be we can optimze this:

msposd/osd/util/Render_x86.c

Lines 1 to 2 in cabc6b8

	//Uncomment when debugging to have access to the windows below the OSD surface
	//#define _DEBUG_x86

msposd/osd/util/Render_x86.c

Lines 73 to 75 in cabc6b8

	#ifdef _DEBUG_x86
	forcefullscreen=false;
	#endif
