Describe the Problem

We are experiencing problems with the compilation of MET-11.1.0-beta2 on Hera, seemingly due to recent SonarQube changes.

Expected Behavior

Resolve the problems to get a successful compilation on Hera. Changes require:

• Adding -std=c++11 to CXXFLAGS in configure.ac
• Adding "std::" to isnan in various places

Environment

Describe your runtime environment:
1. Machine: Hera
2. OS: CentOS Linux 7 rhel fedora
3. Compilers: Using icc (ICC) 2021.5.0 20211109; gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44)

To Reproduce

Describe the steps to reproduce the behavior:
As the role.metplus user, in /contrib/met/11.1.0-beta2, run "./compile_MET_all.sh install_met_env_met_only.hera" or to build manually while testing changes, run "./build_manually.sh"
