I succeed to compile a driver using gcc from Cygwin. To avoid the 
dependency with cygwin.dll, I compile with the option '-mno-cygwin' to 
use the mingw librairies.

My compilation orders are
'g++ -c -mno-cygwin -fpic -shared -I$ERL_INCLUDE_CYGWIN_PATH' for all 
sources.
'g++ -mno-cygwin -fpic -shared -oXXX.dll all_dot_o -llibrary_to_drive'


Hope that this could help you.
