<pre>Hi,
I wonder if having "using namespace" in the root namespace is safe. Probably
not.
I think it is responsible for a conflict between OSX's TimeRecord and the one
in LLVM:
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk/usr/include/MacTypes.h:604:16:
error: reference to 'TimeRecord' is ambiguous
typedef struct TimeRecord TimeRecord;
^
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk/usr/include/MacTypes.h:599:8:
note: candidate found by name lookup is 'TimeRecord'
struct TimeRecord {
