commit 52bb5a596781ddb7f993209ededae5e5df03d2cb
Author: Martin Liska <mliska@suse.cz>
Date:   Thu Jan 27 11:22:42 2022 +0100

    Improve wording for -freport-bug option.
    
    gcc/ChangeLog:
    
            * diagnostic.cc (diagnostic_initialize):
            Initialize report_bug flag.
            (diagnostic_action_after_output):
            Explain that -freport-bug option can be used for pre-processed
            file creation.  Make the message shorter.
            (error_recursion): Rename Internal to internal.
            * diagnostic.h (struct diagnostic_context): New field.
            * opts.cc (common_handle_option): Init the field here.
