What to do about MinGW missing Core Audio headers?

I'm currently trying to build a little C app using Eclipse CDT and MinGW, however I've hit a snag.

I'm looking for devicetopology.h among other header files which were introduced as part of the Core Audio API in Windows Vista.

My question is really "why are 4 year old headers still not in the mingw win32api" - not in the ungrateful sense but more along the lines of is there some technical reason why MinGW can't make use of those libraries?

Any missing defs that I've encountered so far I've just defined in my own source, but I'm apprehensive about importing an entire .h file and I'm unsure of where I'd even source such a file other than the Windows SDK which I imagine was designed to compile under VC. I've found a project called Por开发者_如何学GotAudio (http://www.portaudio.com) which has the headers in their SVN but wished to understand the reasons why the headers aren't included in the first place instead of copy paste coding.

I'd just use VS C++ Express to solve this problem, however I missed some of the features which were gimped the last time I used the C# Express version.

Thanks for any help!

To your last comment - what's missing from Visual C++ Express that you get from using MinGW instead? Note that you can also drive the compiler included with VC++ Express (or the compiler that comes with the Windows SDK) from any IDE that supports driving a command-line build - which is what I'd guess you have to do with MinGW, too.

If it's debugging capabilities that you're looking for, the free Debugging Tools for Windows package that comes with the Windows SDK is quite capable (though the VC++ Express debugger is pretty nice, too).

VC++ Express doesn't have MFC, but then again neither does MinGW. So what's missing from VC++ that's hanging you up?
