Ok, so building gdc on cygwin isn't really difficult: it's just a matter
of having the paths right.
But now that it's ready, I tried compiling a simple program and it
caused an static assert(0) on std.c.windows.windows. Now, cygwin runs on
top of Windows, so shouldn't version Windows be enabled?

I'm not sure. Cygwin is supposed to emulate Unix, and so a true emulation of Unix wouldn't have Windows, since a real Unix doesn't. But since it is in reality running under Windows, I guess that make it somewhat ambiguous.

I guess it depends on whether C/C++ programs under Cygwin can access the Windows API. And I don't know enough about Cygwin to know if that can be done or not.

They can, but typically don't.

Cygwin g++ does not define WIN32.  MinGW g++ does.

gdc should probably mirror this behaviour.

Isn't GNU defined?

That sounds reasonable (even if I still think std.c.windows.windows should be available).

Does it make sense to set Windows/Win32 if the -mno-cygwin option is given?

This should actually be asked on some Cygwin forum! There probably is an established way of doing this -- and we wouldn't want to break it.
