            Bug ID: 270394
           Summary: [GTK] ARM64/A64DOpcode.h fails to compile with "error:
                    ‘once_flag’ in namespace ‘std’ does not name a type"
           Product: WebKit
           Version: Other
          Hardware: Other
                OS: Linux
            Status: NEW
          Keywords: Gtk

          Reporter: morgan at eml.cc

When compiling with "jumbo build" disabled, it seems there's a header file missing a dependency.

I originally reported this to Gentoo (the distro I'm using) here: https://bugs.gentoo.org/925621

I'll attach the full ninja output for the this file.
