Changes in directory llvm/lib/Target/CBackend:

Writer.cpp updated: 1.192 -> 1.193
---
Log message:

Paper over CBackend/2004-08-09-va-end-null.ll

Note that this indicates a serious problem with the way we are emitting varargs,
but this should not be properly fixed until after 1.3.

This patch SHOULD go into 1.3.
