Description Sylvain 2013-08-29 11:29:49 UTC 
I got them with CLang + Android
A few warnings, that could be important : 


jni/SDL_hg/src/thread/pthread/SDL_syssem.c:159:36: warning: comparison of unsigned expression >= 0 is always true [-Wtautological-compare]
        if ((SDL_GetTicks() - end) >= 0) {
            ~~~~~~~~~~~~~~~~~~~~~~ ^  ~


jni/SDL_hg/src/timer/unix/SDL_systimer.c:164:1: warning: control may reach end of Compile thumb  : SDL2 <= SDL_blit_A.c
non-void function [-Wreturn-type]


jni/SDL_hg/src/video/android/SDL_androidgl.c:41:1: warning: type specifier missing, defaults to 'int' [-Wimplicit-int]
Android_GLES_SwapWindow(_THIS, SDL_Window * window)
^~~~~~~~~~~~~~~~~~~~~~~

jni/SDL_hg/src/video/android/SDL_androidgl.c:47:1: warning: control reaches end of non-void function [-Wreturn-type]
}

Comment 2 Sylvain 2013-08-29 18:06:25 UTC 
...and an minor extra one !

jni/SDL_image_hg/IMG_png.c:499:24: note: remove extraneous parentheses around the comparison to silence this warning
    if ( (row_pointers == NULL) ) {
         ~             ^      ~
jni/SDL_image_hg/IMG_png.c:499:24: note: use '=' to turn this equality comparison into an assignment
    if ( (row_pointers == NULL) ) {


And also:

jni/SDL_image_hg/external/jpeg-9/jmem-android.c:135:5: warning: implicit declaration of function 'unlink' is invalid in C99 [-Wimplicit-function-declaration]
    unlink(path);
    ^
jni/SDL_image_hg/external/jpeg-9/jmem-android.c:141:45: warning: implicit declaration of function 'getpid' is invalid in C99 [-Wimplicit-function-declaration]
    snprintf(path, 1023, "/sdcard/.%d.tmp", getpid());
                                            ^


Thanks !
