Repro will not build with GCC-14

[Roland-F]

When i try to build your repro with GCC-14, i got some errors.

jpeg_mem_dest.h: In function 'empty_mem_output_buffer':
jpeg_mem_dest.h:5:27: error: assignment to 'int' from 'char *' makes integer from pointer without a cast [-Wint-conversion]

Any help possible from your side?
With the problem with the build as x86 system, i would prefer to rename the file jpeg_mem_dest.h through jpeg_mem_help.h
and let the function inside still as jpeg_mem_dest().

If you use libjpeg you can remove the include entirely, just needed when using libjpeg-turbo
