Looks good to me (with a minor comment). Thanks!



================
Comment at: clang/tools/driver/driver.cpp:271
+    unsigned long long Enable;
+    if (getAsUnsignedInteger(SpawnCC1Str, 10, Enable) || Enable > 1) {
+      llvm::errs() << "error: the value of the environment variable "
----------------
I think just checking SpawnCC1Str == "0" or == "1" would be easier.
