/* ERROR/WARNING messages:

E: Cannot open gzipped file

LAMMPS was compiled without support for reading and writing gzipped
files through a pipeline to the gzip program with -DLAMMPS_GZIP.

E: Cannot open file %s

The specified file cannot be opened.  Check that the path and name are
correct. If the file is a compressed file, also check that the gzip
executable can be found and run.
