[gdal-dev] [PROJ] RFC 102: Embedding resource files into libgdal (and PROJ)

[Even Rouault]

The RFC is clear enough this is an optional feature ("C23 is not 
required if EMBED_RESOURCE_FILES is not enabled"). If you need it, you 
will need a C23 compiler, which there is already one available (clang 
19), and another one in a near future (gcc 15).

C23 is only used to build the .c files where resources are embedded.

If you don't need that new feature, you can use the current minimum 
build requirements of GDAL/PROJ.

For once that GDAL/PROJ can use shiny new stuff, let's enjoy :-)

No way a gcc from 6 years ago can support #embed: support has literally 
landed in GCC master 2 weeks ago.
