From 2681510db63a94fdb8f14c50bf0265dcdfceef65 Mon Sep 17 00:00:00 2001 From: redi Date: Thu, 26 Jul 2018 14:02:01 +0000 Subject: [PATCH] Remove char16_t and char32_t dependency on The char16_t and char32_t types are automatically defined by the compiler and do not depend on support in . The char_traits specializations depend on uint_leastNN_t but can be made to work anyway by using the predefined macros, or as a last resort make_unsigned. * include/bits/basic_string.h [!_GLIBCXX_USE_C99_STDINT_TR1] (hash, hash): Remove dependency on _GLIBCXX_USE_C99_STDINT_TR1. * include/bits/char_traits.h [!_GLIBCXX_USE_C99_STDINT_TR1] (char_traits, char_traits): Remove dependency on _GLIBCXX_USE_C99_STDINT_TR1.
