Yes, in Cygwin you usually configure a project for a real Unix target.
Sometimes you set some flags that this it "not win32" to avoid MS-specific 
non-Posix settings.
I think, UHD should be Cygwin-compatible in principle (when it's not using raw 
sockets).
I could compile it but some binaries crashed with a core dump. Sorry, I deleted
the directory later, so I can't provide you a crash report now. Perhaps later 
for a next try.
In general I think Cygwin should be a supported platform for UHD, because it's 
a GNU
"operating system", without GNU kernel, but with almost all the rest of GNU.

I had much of this mixing experience in Matlab. It's a horror. You can't really 
connect
these two worlds, because the Cygwin gcc uses a different exception handling 
system
as Windows programs. The runtimes are not compatible. Trying to connect binary 
code
via DLL, especially external MEX-functions in MATLAB, will lead to mysterious 
crashes.
I'm using gcc to compile Mex-code (linked to lots of other libs), but I have to 
call the
mingw-gcc with a windows-compatible runtime library.

The clean way is to keep a complete POSIX parallel world inside your windows 
box.
That's why my X-Server is constantly running (in seamless windows mode).
You feel "at home" there, don't need to deal with the strange MSVC compiler 
options,
code and autoconf build systems are mostly compatible ....
There is lots of open source software, math and signal processing libraries that
run in Cygwin without modifications, but not with MSVC.

wxWindows, wxPython etc. were difficult to configure, but it works.
Some of the packages you will find in the alternative "cygwin ports" repository.
