It's tempting to ask why not...

But I guess there must be someone who has released binaries for this, if 
I decide that's what I want.

Aren't the normal users those who have to support multiple platforms? It 
seems to me that it must be better to have the same build host for most 
or all of them...

Personally, I think I may possibly be talked into developing software 
for Windows, but only if I don't have to do actual work under the 
Windows environment, which I just don't like (that's why I'm here, right?)

Where do these come from? The gcc distro itself? glibc?

I did have a stab at building a "cross gcc" for cygwin target, but I was 
using my newlib-based setup for embedded platforms, which I didn't 
really expect to work. And I was right. The build looked promising for a 
while, but eventually failed due to missing stdio.h or something like 
that. I didn't investigate the issue further.
