     Fortran: Fix failures on windows and hpux systems [PR124330]

     Co-authored-by: John David Anglin <[email protected]>

             PR fortran/124330

     libgfortran/ChangeLog:

             * caf/shmem/shared_memory.c: Fix filenames for WIN32
             includes.
             (shared_memory_set_env): Use putenv() for HPUX and as
             a fallback where setenv () is not available.
             (NAME_MAX): Replace with SHM_NAME_MAX.
             (SHM_NAME_MAX): Use this to avoid duplicating NAME_MAX
             used elsewhere.
             * caf/shmem/supervisor.c (get_image_num_from_envvar): Add
             a fallback for HPUX. Add additional comment to explain why
             the number of cores is used in lieu of GFORTRAN_NUM_IMAGES.
