This change caused problems when building code like povray that: a) uses 'using namespace std;' b) is built on an environment where the C library provides the "wrong" (non-const-correct) interface for the str* functions c) makes an unqualified call to one of those str* functions A patch is out for review to add a facility to fix this (and to give the correct signatures for these functions whenever possible, even when the C library does not do so). This revert is expected to be temporary. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@251665 91177308-0d34-0410-b5e6-96231b3b80d8
