cln::foo instead of cl_foo, except where the cl_ comes from a data type

(as in cl_I_to_int()). Headers are installed into a separate

C integers.
|
| 225 |
|
|
|

(Suggested by the LiDIA group.)
|

the resulting float depending on the number of significant digits present

| 257 |
|

in the input string.

`type::type (const long)' and `type::type (const unsigned long)'
