Sudden-death static asserts were introduced due to comment #2 of bugzilla 77:
http://d.puremagic.com/issues/show_bug.cgi?id=77

However, they make static assert rather useless, since it gives you absolutely
no context. To make it useful again,

In staticassert.c, line 68 (in DMD2.027):
        error("is false");
        if (!global.gag)
            fatal();
---
change this to:
        error("(%s) is false", exp->toChars());
---

(ie, remove the global.gag test).
