CHEUI preprocess C++ compiling issue

[seungbeom-han]

Hello, I'm trying to compile preprocessing C++ file, but I got an expected identifier error. This occurs in ocavlhash.h and ocordavlhash.h file used in PicklingTools (line 924 in the code below). Are there any way to successfully compile the code? To note, I compiled the C++ code in Ubuntu 22.04 with g++ 11.4.0.
