mpich-default @4.0.3: Configuration logfiles contain indications of -Wimplicit-function-declaration

Configuration logfiles contain indications of -Wimplicit-function-declaration:

--->  Configuring mpich-default

  exit: found in mpich-4.0.3/modules/json-c/config.log

I don't know about the others but certainly the implicit declaration of exit is a mistake. From main.log:

:info:configure checking for __thread support... no

From config.log:

I have the same message after a fresh install of MacPorts on Monterey 12.6.3. Is that disrupting use of mpich?

FYI, I also have similar message with openmpi-default:

Warning: Configuration logfiles contain indications of -Wimplicit-function-declaration; check that features were not accidentally disabled:
  CPU_ALLOC_SIZE: found in build/config.log
  process_vm_writev: found in build/config.log
  CPU_FREE: found in build/config.log
  CPU_SET_S: found in build/config.log
  CPU_ZERO_S: found in build/config.log
  process_vm_readv: found in build/config.log
  CPU_ALLOC: found in build/config.log
  CPU_SET: found in build/config.log
  CPU_ZERO: found in build/config.log

In both cases, it prevents me to install the port py311-mpi4py (with mpich or openmpi variant).
