I'm in the same situation... I can continue development on the board, but 
would prefer to make some system-independent things on synthetic :)

It is just what I'm trying now. Sure, I've installed new compiler into 
another directory. And, of course, CYGBLD_GLOBAL_COMMAND_PREFIX (ecos.ecc) 
is changed to point to 3.0.4 location. CYGBLD_GLOBAL_LDFLAGS is also changed 
 - vtable-gc is removed as it becomes unnescesary.

Looks a bit dangereous.. :) But anyway - thanks! 

May be I need to indicate some other library except ecoswide standard 
../install/lib directory...? 

Could I ask you to tell me if your gcc build will be successeful? 

Thank you!
Dmitry.
