Error: this declaration has no storage class or type specifier

Hi to all
I am working on encryption AES Algorithm on LPC1768.
The problem comes when I compile the project from Keil. I got this log:
Any pointers or suggestion will be helpful.

I am using the latest version of the toolchain, Keil V5 and the pack for my controller is updated. Any idea about where can be the problem?

Thanks in advance
