clang 3.1 which is shipping with Xcode 4.3 ("based on LLVM 3.1svn") seems to
insert extra spaces in macro expansions.

A test case:

$ cat foo.h 
#define VALUE 2012-02-19
Output: VALUE

$ clang -E -P foo.h 

Output: 2012 -02 -19

$ gcc -E -P foo.h 



Output: 2012-02-19


$ clang --version
Apple clang version 3.1 (tags/Apple/clang-318.0.45) (based on LLVM 3.1svn)
Target: x86_64-apple-darwin11.3.0
Thread model: posix
