The change you made is not really a problem, but it raises an issue:
as of today, I don't believe we ought to fight against bugs in C++
compilers.  The code we produce is compliant with a (pretty-)well
defined standard.

Alternatively, these guys could have been declared here, and
instantiated in the *.cc file.  Butt that's less pleasing, since they
are "less" self-contained.
