[CPMD-list] compiling warings but it works

[liu liuxiandong]

Dear all,

I make CPMD-3.11.1 on Xeon-CPU linux cluster, and got the following
warnings. But the compilation is successful and the cpmd.x indeed works for
several tests. I am not sure what the warings mean. Thanks for any
suggestions.
Best.
