Compiler/CCSTUDIO-MSP: "error #85: invalid combination of type specifiers" when compiling older version of MSP430 project using new compiler version "TI v18.1.2.LTS"

Part Number:CCSTUDIO-MSP

Tool/software: TI C/C++ Compiler

Hello,

After that I upgraded my CCS IDE version 6 (compile version TI v4.3.3) to 8 (compiler version TI v.18.1.2.LTS), I imported one of my projects from CCS version 6 to 8 and compiled it.  It gave lots of error #85 (please see attached screenshot).

What do I have to do to resolve that?

Thanks.

S
