[cfe-dev] RC1 compilation error with 10.6 SDK

[Benjamin Kramer]

Hi Bill,

I believe the reason for this behavior is that r142531 is missing from the release_30 branch.
Can you squeeze it in? It's important and already Doug-approved.

Correct function can be verified on OSX and xcode4.2 with
$ clang -cc1 -fsyntax-only /Developer/SDKs/MacOSX10.6.sdk/usr/include/unistd.h
