Hi,

Please find attached a patch (gcc15_fix_cap2.patch) which fixes the 
CAP2.c build failures with GCC 15 on ppc64el. The issue was caused by 
incorrect function prototypes in CAP2.c. This patch corrects the 
function signatures and ensures consistent ANSI-style declarations.

Built and tested successfully on ppc64el with GCC 15.

Note: there are still other Altivec/Eigen-related errors in the code, so 
the full build is still failing. Those need to be addressed in a 
separate patch.

I would appreciate a review of this patch and any suggestions for 
improvements.


Thanks,
Trupti
