[Skyeye-developer] what are the semantics of NO_DBCT=1

[Michael.Kang]

I have not installed MACOS. I have a quick look the source of
SkyEye.Maybe some issues existing the following code:
in arch/arm/dbct/arm2x86.c:

//chy 2005-05-11
#if !(defined(__CYGWIN__) || defined(__MINGW32__))
volatile uint32_t arm2x86_pfun;
#else
volatile void (*arm2x86_pfun) (void);
#endif

In different system, maybe function pointer defination is also
different. I am not sure.
