Hi all,

Some small improvements for constify. I slighty optimized the Makefile and remove useless new lines in constify.c when printing version.

In this optimized version, I made the following improvements:

• Consolidated common flags into CFLAGS and DEFINES variables
• Uses := instead of = for variable assignment to prevent unnecessary re-evaluation.
• Uses $(shell date +%Y%m%d) instead of invoking the date command multiple times.
• Moved the platform-specific LIBS flag into an ifeq block for better readability
• Simplified the object file generation rule to use a pattern rule instead of repeating the recipe for each object file
• Added quotes around $@ and $< in recipe commands to handle filenames with spaces (maybe useful for Windows target)
• Added dependencies for the install target to ensure that the executable is built before it's copied to the destination directory

For the constify.c source file, I just removed the \n\n for the PrintVersion function.
