From 6fb99666f4bbc79708acb8efb2d80e57de67b80b Mon Sep 17 00:00:00 2001 From: Ciaran Woodward Date: Tue, 6 Feb 2024 17:56:07 +0000 Subject: Remove use of scoped_restore_tmpl from scoped_restore_warning_hook The warning_hook_handler function pointer takes va_list as an argument, which on some platforms (mingw64) includes some attributes. Attributes get ignored in template arguments. This led to the compiler warning: error: ignoring attributes on template argument 'warning_hook_handler' {aka 'void (*)(const char*, char*)'} [-Werror=ignored-attributes] 387 | scoped_restore_tmpl m_save; | ^ By manually implementing the save/restore behaviour, rather than using the helper template, this warning is fixed.
