[netCDF #BCP-575554]: Error found

Hello,

The example found in the documentation is a shorter example that highlights the 
syntax; it is not meant to be a complete example.

For an example of working with compound types I would refer you to the file 
`nc_test4/tst_compounds.c`, as well as the tst_compounds2.c and 
tst_compounds3.c files in the same directory.  They provide a complete example 
of working with compound types, which should compile for you without problem.

I hope this helps!
