 They don't exist in the library, so you can't access them directly via
 ctypes in the same way as variables (i.e.
 ctypes.CDLL("libgrass_gis.so").GNAME_MAX won't work). However, ctypesgen
 includes preprocessor macros in the generated files, so they are present
 in the grass.lib.*.py modules.

 Even so, simply importing grass.lib.* will load the corresponding dynamic
 library, which may kill the importing process if there are any problems
 (e.g. architecture or version mismatches), so I wouldn't recommend it.
