necessary if we want to avoid duplicating the information. There

are three different modes:

- PROCINFO_DECL is defined. This means we are only interested in

- PROCINFO_DECL is not defined:

+ if SHARED is defined the file is included in an array

initializer. The .element = { ... } syntax is needed.
|

+ if SHARED is not defined a normal array initialization is

needed.
