 Confirmed with cygwin 3.2. Redux:
 
 -----------------------------------------
 struct __attribute__((dllimport)) Foo
 {
  static int static_func();
 };
 
 int bar = Foo::static_func();
 
 int Foo::static_func()
 {
  return 0;
 }
 -----------------------------------------
 $ g++ -c pr8378.cpp
 pr8378.cpp: In static member function `static int Foo::static_func()':
 pr8378.cpp:12: Internal compiler error in rest_of_compilation, at
 toplev.c:3491
 Please submit a full bug report,
 with preprocessed source if appropriate.
 See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
 
 Notice this is a regression from 2.95:
 
 $ g++-2 -c pr8378.cpp
 pr8378.cpp: In function `static int Foo::static_func()':
 pr8378.cpp:10: warning: inconsistent dll linkage for `static int
 Foo::static_fun
 c()'. dllexport assumed.
 
 If the definiiton of the variable "bar" is moved after the definition of the
 static function, the ICE disappears and GCC 3.2 emits a warning message just
 like 2.95.
 Synopsis can now be changed to something more appropriate, and class too
 (it's ice-on-legal-code).
