Subject: [PATCH 3/4] fix(build): update JPEG library usage to libjpeg.so.8

- Update Make.config to use JPEG version 80 (libjpeg.so.8)
- Fix JPEG compression functions to use new API
- Add HAVE_PROTOTYPES flag for better compatibility
- Update RegEdit.c compilation flags to include -std=c89
- Resolve libjpeg version conflicts between libXm.so and fbida

This ensures all fbida tools consistently link against libjpeg.so.8
instead of the older libjpeg.so.62, eliminating linker warnings.
