[Bug libstdc++/44952] #include <iostream> implies global constructor.

["paolo dot carlini at oracle dot com" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #9 from paolo dot carlini at oracle dot com  2010-07-15 18:26 -------
Let's say we remove that horrible .h from the Summary, since, to be fair,
didn't exist in g.C in the first place ;)

That said, I agree with Jon, by and large, with the following minor additional
observations: 1- I'm pretty sure the library is correct, but we should double
check whether other established and new implementations of the C++ runtime are
trying to do something special, performance-wise - low priority I'm afraid; 2-
As library maintainers we certainly welcome any improvement to the optimizers
improving the code GCC generates for these constructors, because certainly many
user applications could benefit, not just because the library would; -3 While
we are at it, I think we should make sure not regressing on libstdc++/39796, or
even making progress at once. Ideas? (I didn't really manage to study it in any
detail)
