The SDL_MouseMotionEvent struct has a field named "tilt" (currently marked "for
future use"), for tablet stylus tilt information.  However, one value is not
enough for this, as tilt is two-dimensional.  Reserving only one field for
future use is no good when you're going to need two, so there should be two
fields, tilt_x and tilt_y.

Patch to use stdlib.h with Open Watcom

Open Watcom 1.8 has <stdlib.h> so instead of patch the single part when stdlib
features are used we use directly the include file as with GCC.

      Fixed bug #905 · 08bbf9ac
      Sam Lantinga authored 
      Give the foreign window message proc more control over Windows events.

This may need to be adjusted when we add the capability for the app to specify whether it wants SDL to handle input for the window or not.

Originally reported by AKFoerster on the mailing list.

Error decoding UTF8 Russian text to UTF-16LE on Windows, but specifically on
platforms without iconv support (the default on Windows).

Valid UTF8 characters are flagged as being overlong and then substituted by the
UNKNOWN_UNICODE character.

After studying the testiconv.c example program, reading the RFCs and putting
some printf statements in SDL_iconv.c the problem is in a test for 'Maximum
overlong sequences', specifically 4.2.1, which is carried out by the following
code:

      } else if ( p[0] >= 0xC0 ) {
        if ( (p[0] & 0xE0) != 0xC0 ) {
          /* Skip illegal sequences
            return SDL_ICONV_EILSEQ;
          */
          ch = UNKNOWN_UNICODE;
        } else {
          if ( (p[0] & 0xCE) == 0xC0 ) {    <<<<<<<< here
            overlong = SDL_TRUE;
          }
          ch = (Uint32)(p[0] & 0x1F);
          left = 1;
        }
      } else {

Here is the 2-byte encoding of a character in range 00000080 - 000007FF
    110xxxxx 10xxxxxx

The line in question is supposed to be checking for an overlong sequence which
would be less than
    11000001 10111111

which should be represented as a single byte.

BUT, the mask value (0xCE) is wrong, it isn't checking the top-most bit:
    11000001     value
    11001110     mask (incorrect)
       ^
and should be (0xDE):
    11000001     value
    11011110     mask (correct)

making the above code:

      } else if ( p[0] >= 0xC0 ) {
        if ( (p[0] & 0xE0) != 0xC0 ) {
          /* Skip illegal sequences
            return SDL_ICONV_EILSEQ;
          */
          ch = UNKNOWN_UNICODE;
        } else {
          if ( (p[0] & 0xDE) == 0xC0 ) {    <<<<<<<< here
            overlong = SDL_TRUE;
          }
          ch = (Uint32)(p[0] & 0x1F);
          left = 1;
        }
      } else {

I can supply a test program and/or a patch if required,

best regards,
John Popplewell
