Re: new compiler warnings in freetype 2.10.2 32-bit

[Vincent Torri]

hello

some comments:

strcasecmp does not exist when compiling with Visual Studio (_stricmp
does though and is doing the same job). mingw-w64 use a #define for
that.Why not adding ft_strcasecmp like ft_strdup ?

note that using strdup with Visual Studio and passing
_CRT_NONSTDC_NO_DEPRECATE removes the warning.
