It's not that I didn't want to, it's just that I was wondering if there was 
a better way.

Fortunately, version(System) is exactly what I needed in my specific case, 
even if it isn't a general solution.

These doesn't appear to work:

--
version(Windows)
{
enum callingConvention = "Windows";
}
else
{
enum callingConvention = "C";
}

extern(mixin(callingConvention ))
{
/+ ...code here... +/
}
--
version(Windows)
{
extern(Windows):
}
else
{
extern(C):
}

/+ ...code here... +/

extern(D):
--



does this work?

private void fnImpl(...)
{
   // code here
}

version(Windows)
{
   extern(Windows) fn(...) {fnImpl();}
}
else
{
   extern(C) fn(...) {fnImpl();}
}

Ouh, haven't read that you don't want code to be mixed-in.. In that
case.. I dunno :)

If I'm not mistaken extern() accepts only Identifier, not expression.
I'm not really sure what's the best way to do that but I belive this
should work (haven't tested):

enum code = q{

   void func() {
   // do something
   }
};

version (Windows) {
   extern (Windows) {
   mixin(code);
   }
} else {
   extern (C) {
   mixin(code);
   }
}

That specific pair of extern types with that specific set of versions 
--> extern(System)

Versioned extern?

Is there a way to have a section of code be extern(C) on one OS and 
extern(Windows) on another OS, without resorting making the code in question 
a mixin?

These doesn't appear to work:

--
version(Windows)
{
enum callingConvention = "Windows";
}
else
{
enum callingConvention = "C";
}

extern(mixin(callingConvention ))
{
/+ ...code here... +/
}
--
version(Windows)
{
extern(Windows):
}
else
{
extern(C):
}

/+ ...code here... +/

extern(D):
--
