I don't think that's a good idea. Cygwin is meant for Unix applications that 
have not been ported to Windows. Qt does not work under cygwin. It uses the 
native Win32 API and expects it to be have like Windows, not like a 
bastardised Unix.

And you cannot mix libraries built for one with libraries built for the other. 
The base C library is different.

As for the issue of the GCC version being old, feel free to get a newer 
version of MinGW. The Qt 4.8.6 pre-release packages are now built with a new 
MinGW too:

The only advice I can give is to use paths without spaces. Any tooling that 
uses space-separated lists, like qmake and make, are bound to have problems 
with paths containing spaces.
