new compiler warnings in freetype 2.10.2 32-bit

[Hin-Tak Leung]

Hi,

There seems to be a new warning in 2.10.2 (compared to 2.10.1) when compiling 
for 32-bit:

===
freetype-2.10.2/src/sfnt/sfwoff2.c:327:39: warning: passing argument 3 of 
'BrotliDecoderDecompress' from incompatible pointer type 
[-Wincompatible-pointer-types]
  327 |                                       &uncompressed_size,
      |                                       ^~~~~~~~~~~~~~~~~~
      |                                       |
      |                                       FT_ULong * {aka long unsigned int 
*}

Also have had a bunch of strncat related warning (probably gcc 10 specific, or 
some compiler switch specific) in ft2-demos, for a while:

Argh, that's just one line in ttdebug which generates multiple warnings, plus 
another one in ftcommon.c

I haven't gotten round to look at either, just in case somebody are bothered 
enough to have a look...
