As a result of this change(*), libc++ fails to compile for me:


+ clang++ -c -g -Os -fPIC -std=c++0x -fstrict-aliasing -Wall -Wextra -Wshadow
-Wconversion -Wnewline-eof -Wpadded -Wmissing-prototypes -Wstrict-aliasing=2
-Wstrict-overflow=4 -nostdinc++ -I../include ../src/future.cpp

    case future_errc::no_state:

4 errors generated.

This is on linux with clang from git.

(*) `git bisect` told me.
