Subject: Explicitly request unsigned enum types when desired
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=73f615b0bd822db3a2a8aab2fd4ed58f093c9769;p=oota-llvm.git

Explicitly request unsigned enum types when desired

This fixes repeated -Wmicrosoft warnings when self-hosting clang on
Windows, and gets us real unsigned enum types with MSVC.
