Compiling master branch fails with parentheses errors

[adenchfi]

Hello,
The master branch seems to have some parentheses errors that the Comscope2021SummerSchool branch does not. Perhaps the Intel compiler does not catch these; I am instead compiling with gcc-9.2.0, and compilation is failing with the following errors:

whereas the Comscope2021SummerSchool branch compiles successfully with the same parameters. Side note, the ComCTQMC/evalsim and /host makefiles have -lmpi_cxx in this branch also yield errors [I am using mpicc here] but removing them works.
