From: Jonathan Wakely Date: Wed, 30 Oct 2019 15:48:23 +0000 (+0000) Subject: Remove some more using-declarations from namespace __gnu_cxx X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d03eca30d746a097635d8dedc9e059c6b2f80907;p=gcc.git Remove some more using-declarations from namespace __gnu_cxx Similar to some recent patches, this removes using-declarations for names from namespace std, so that they are not redeclared in __gnu_cxx. * include/bits/stl_iterator.h (namespace __gnu_cxx): Remove using-declarations for std::iterator and std::iterator_traits. (__gnu_cxx::__normal_iterator): Qualify iterator_traits. * include/ext/algorithm (namespace __gnu_cxx): Remove using-declarations for std names and qualify those names when used. Also refer to std::min in parentheses to protect against function-like macros. * include/ext/rc_string_base.h: Qualify iterator_traits. * include/ext/sso_string_base.h: Qualify iterator_traits.
