Hello,

The build fails with GCC 14+ because some functions in CAP2.c are 
written in an old C style.
Earlier GCC versions allowed this, but new compilers treat them as 
functions with no arguments.
So calls like my_calloc(1) or ckopen(file,mode) now give errors.
The code needs to be updated with proper function declarations.

I will work on preparing a patch to fix this.


Thanks,
Trupti
