Thanks for working on this! (It's nice when all the tests succeed:-)

This "problem" only shows up when clang parses the preprocessed file.
It works fine when parsing the original source.
Here is a comment I added to Sema::MergeTypeDefDecl awhile ago:
// Redeclaration of a type is a constraint violation (6.7.2.3p1).
// Apparently GCC, Intel, and Sun all silently ignore the
redeclaration if
// *either* declaration is in a system header. The code below
implements
// this adhoc compatibility rule. FIXME: The following code will not
// work properly when compiling ".i" files (containing preprocessed
output).
