New implicit-fallthrough warnings with JUCE 9.0.1 on Xcode

MacOSX and iOS
1

With JUCE 9.0.1, Xcode reports new implicit-fallthrough warnings when XCODE_ATTRIBUTE_CLANG_WARN_IMPLICIT_FALLTHROUGH is set to "YES".

This can be fixed by adding Wimplicit-fallthrough to the JUCE_BEGIN_IGNORE_WARNINGS_GCC_LIKE declarations in the following files:

  • modules/juce_graphics/juce_core_zlib.c

  • modules/juce_graphics/juce_graphics_libjpg_1.c

  • modules/juce_graphics/juce_graphics_libjpg_2.c

  • modules/juce_graphics/juce_graphics_libjpg_3.c

  • modules/juce_graphics/juce_graphics_libpng.c

  • modules/juce_graphics/juce_graphics_lunasvg.c

This should suppress the warnings for these third-party/generated sources while keeping CLANG_WARN_IMPLICIT_FALLTHROUGH enabled for the rest of the project.
