The code
alias A B;
const int A = 1;
causes error
test.d(1): Error: alias test.B forward reference of A
This is caused by dmd not trusting it's forward reference capabilities and
issuing the error without even trying:
Index: declaration.c

//printf("alias is a symbol %s %s\n", s->kind(), s->toChars());
type = NULL;
VarDeclaration *v = s->isVarDeclaration();

(I thought this would be a duplicate, but the patch does not apply to any other
bug i've tried).
