[cfe-dev] 回复： Clang/C++ problem?

[jiyang zhao]

No, it should not work, because (i think) it is similar with the code as follows,
unsigned int int var = 0;
your problem is that you treat the typedef as macro here, so you think when processing unsigned Foo_t, it should be treated as unsigned int. 
But, again, it's not macro.

Shouldn't this work?
If it should work, should I write up a bug?

$ cat junk.cpp
> typedef int Foo_t;

$ g++ junk.cpp

$ clang junk.cpp
