NetCDF-c Github issue #178 / esupport BNL-694121
The ncgen man pages says:
> Note also that the words variable',dimension', data',group', and
> `types' are legal CDL names, but be careful that there is a space be-
> tween them and any following colon character when used as a variable
> name. This is mostly an issue with attribute declarations.
Ncdump does not obey this rule.
The fix is to modify ncdump/ncdump.c to check if a variable name is
a keyword.
Also added test case.
The code for handling character constants
in datalists in ncgen has some problems.
1. It failed on large constants
2. It did not handle e.g. var = 'a', 'b', ...
in the same way that ncgen3 did.
3. The code for generate.c and genchar.c needed
some refactoring to make it a little simpler
(but not simple).
