I'm trying to read from the registry (thus far unsuccesfully). 
core.sys.windows.windows has RegOpenKeyExA() in it, and I'm trying to use it to 
read a registry key. However, when I use it, I get this error upon compilation:

Error 42: Symbol Undefined _RegOpenKeyExA 20

I'm using wine, and according to 
http://source.winehq.org/WineAPI/RegOpenKeyExA.html it appears to be 
implemented. So, what on earth could I be missing? Any help would be much 
appreciated.

This function isn't implemented in Phobos, it's implemented in advapi32.dll
You either need to link with advapi32.lib or a linkage.def file with the  
following contents (without quotes):

"EXETYPE NT

IMPORTS
_RegOpenKeyExA 20 = advapi32.RegOpenKeyExA"

Hope that helps.

I haven't had this problem with any other windows calls that I've used. As long 
as they've been in druntime, they've worked. Are you suggesting that that's the 
case because Phobos or druntime also happened to link aganst any of the other 
windows functions that I've used, and that in this case, they don't, so I have 
to link it explicitly?

Yes, it links with some of the libraries implicitly.

It looks liking adding advapi32.lib to the compilation command does the trick, 
but I don't know why I've never needed to do that before with other Windows 
functions.

Just guessing, but it might be that dmd doesn't add advapi32.dll to the 
linker's command line by default.  You can probably verify that by 
passing -v to dmd, to see the linker commands being used.
