Installation of unifdef

First, fix a problem when building with gcc-15: 

sed -i 's/constexpr/unifdef_&/g' unifdef.c

Now fix a problem if reinstalling the package: 

sed -i 's/ln -s/ln -sf/' Makefile

Install unifdef by running the following commands: 

make

To test the results, issue: LC_ALL=C make test.

Finally, finish the installation as the root user:
