Martin Sebor commented on STDCXX-755:
-------------------------------------
Hmm. I see a bunch or remarks and a couple of instances of warning #2177 but no
#20200. I already silenced the remark #4300 from <iomanip> in
[r643078|http://svn.apache.org/viewvc?view=rev&revision=643078]. Remark #4298
from _localedef.h is annoying and causes a lot of noise in many compilations
(by my count there were 95 instances of it as of last Friday) but I haven't
been able to bring myself to uglify the code enough to silence it yet...
