When using Win32/x86 in a version block, does that relate to the 
compiler or OS?

for example:

version(Win32)
{
     // 32bit Windows or 32bit Compiler?
}

version(X86)
{
     // 32bit OS or 32bit Compiler?
}

If these don't relate to the compiler is there any indication 
that the program is being compiled with a 32bit compiler?

I'm primarily asking because i need to use this to constrain dub 
to build different things depending on what compiler is used and 
on what architecture.

version arguments are for the target architecture, not the 
compiler/build-environment.

You might want to use: D_LP64 - Pointers are 64 bits (command line 
switch -m64). (Do not confuse this with C's LP64 model)

I don't think what you're asking for is useful. The 32bit compiler can 
compile both 32bit and 64bit code, at least DMD.

 architecture.

GNU - GDC
LDC - LDC
