GCC 13 compilation errors due to missing headers

Users may encounter the following errors when compiling a C++ program with GCC 13:

error: 'uint64_t' in namespace 'std' does not name a type

Several applications using OpenMPI, including HDF5, Boost, Rmpi, ORCA, and CP2K, may fail with errors such as

mca_coll_hcoll_module_enable() coll_hcol: mca_coll_hcoll_save_coll_handlers failed

Caught signal 11: segmentation fault

We have identified that the issue is related to HCOLL (Hierarchical Collectives) being enabled in OpenMPI.
