 #else

 #endif
 
 If I move the parentheses out of the conditional code it compiles 
 without errors.

+Here's a simpler test case:
+
+1 interface IFoo {}
+2 interface IBar : IFoo {}
+3
+4 class A : IFoo, IBar {}
+5
+6 class X {
+7	static void Main ()
+8	{
+9		A a = new A ();
+10		IFoo b = 
+11 #if FOO
+12		(IFoo)
+13 #else
+14		(IBar)
+15 #endif
+16		a;
+17	}
+18 }
+
+With some debugging code inserted, here's what I see:
+
+mcs -debug 74939.cs
+handle_preprocessing_directive, c is '#' at 11
+cont is False
+round we go again
+handle_preprocessing_directive, c is '#' at 13
+#else: 1
+cont is True
+handle_preprocessing_directive, c is '#' at 15
+cont is True
+handle_preprocessing_directive, c is '#' at 17
+74939.cs(18) error CS1028: Unexpected processor directive (no #if for
+this #endif)
+cont is True
+Compilation failed: 1 error(s), 0 warnings
+
+For some reason, we're calling handle_preprocessing_directive even
+after we're done with them (at line 17)
