Most definitely, it is wrong.  It built, but I had interrupted the 
testing process to add another unrelated change.  That's my bad.

However, fundamentally the code in glibc as it exists today is wrong as 
well.  It's just wrong in a way that is amazingly hard to test.

If it's just convention, then we need to make it a strict policy.  I'm 
fine with that.
