Not sure how important it is to have the constants the poster is mentioning below. Initially
it seems like a pretty straight-forward addition to winnt.h.
Also would enable an api call (NT4 Only):
BOOL IsProcessorFeaturePresent (
DWORD <processor feature>
kernel32.dll (both NT4 & XP-Pro) has a reference to it. Don't have Win2k, so can't say if
it also has IsProcessorFeaturePresent() api call.
A quick review on PF_* (win32api online docs, back in 1996) yields the following
constants as part of Win32api:
when invoking IsProcessorFeaturePresent() [NT4 and XP].
The thing is, s/he wasn't clear as to why it was necessary since most of the results the
constants provide from IsProcessorFeaturePresent() can be deduced using GetSystemInfo() and
knowing what type of processor is in your desktop box (mips, alpha, ppc, etc.).

I've found the winnt.h header file on MinGW lacks the following constant
#define PF_FLOATING_POINT_PRECISION_ERRATA 0
#define PF_FLOATING_POINT_EMULATED 1
#define PF_COMPARE_EXCHANGE_DOUBLE 2
#define PF_MMX_INSTRUCTIONS_AVAILABLE 3
#define PF_PPC_MOVEMEM_64BIT_OK 4
#define PF_ALPHA_BYTE_INSTRUCTIONS 5
#define PF_XMMI_INSTRUCTIONS_AVAILABLE 6
#define PF_AMD3D_INSTRUCTIONS_AVAILABLE 7
These constants doesn't appear on MinGW 1.1.
I don't know how to send this to the appropriate person, so it would be
great if anyone can light me on that.
