// Detect a number of compiler features - by compiler
Reorganised C+11 feature detection a bit and added CATCH_CONFIG_CPP11_NULLPTR for VS2015
2015-05-19 19:37:58 +02:00
// The following features are defined:
//
Use __COUNTER__ when generating unique names instead of __LINE__, if available. Based on PR #351
2015-12-15 08:50:51 +01:00
// CATCH_CONFIG_COUNTER : is the __COUNTER__ macro supported?
Fixes for MinGW compatibility Some versions of MinGW do not support enough of Win32 API to let us work with SEH, so SEH is now MSVC only (+ configurable toggle). Also made use of gmtime_s MSVC only (as oposed to Windows only). Fixes #805

Added unique_ptr detection to compiler_capabilities - as well as use by C++11 conformant compilers now enabled for VS2013 on too (see #479) - updated docs with this (and long long and override support)
