When trying to compile on a Raspberry Pi 3, running Raspbian Stretch (fully updated), a warning appears:
/home/pi/projects/SDL/src/test/SDL_test_memory.c: In function ‘SDL_TrackAllocation’:
/home/pi/projects/SDL/src/test/SDL_test_memory.c:112:109: warning: format ‘%llx’ expects argument of type ‘long long unsigned int’, but argument 5 has type ‘unw_word_t {aka unsigned int}’ [-Wformat=]
snprintf(entry->stack_names[stack_index], sizeof(entry->stack_names[stack_index]), "%s+0x%llx", sym, offset);
First: disable d'n'd events by default; most apps don't need these at all, and
if an app doesn't explicitly handle these, each drop on the window will cause
a memory leak if the events are enabled. This follows the guidelines we have
for SDL_TEXTINPUT events already.
Second: when events are enabled or disabled, signal the video layer, as it
might be able to inform the OS, causing UI changes or optimizations (for
example, dropping a file icon on a Cocoa app that isn't accepting drops will
cause macOS to show a rejection animation instead of the drop operation just
vanishing into the ether, X11 might show a different cursor when dragging
onto an accepting window, etc).
Third: fill in the drop event details in the test library and enable the
events in testwm.c for making sure this all works as expected.
SDL_ExitProcess(), SDL_AbortAssertion() and SDLTest_BailOut().
(Commit c8b4a5166613 for bug #4100 removed SDL_NORETURN from
SDL_ExitProcess() and SDL_AbortAssertion() in order to avoid
warnings from windows builds, but that's temporary I guess..)

These are the remaining compiler warnings I see in the current tip b3bb3855bc41.
- SDL_test_log.c defines _CRT_SECURE_NO_WARNINGS without checking if it was already set.
- SDL_windowskeyboard.c converts integers to pointers without going over the (U)INT_PTR types. That bothers MSVC.

Alt-Up/Down/Left/Right switches between displays using SDL_WINDOWPOS_CENTERED_DISPLAY
Shift-Up/Down/Left/Right shifts the window by 100px
This is currently implemented for X11, Cocoa, Windows, and DirectFB.
This patch is based on work in Unreal Engine 4's fork of SDL,
