23 | All the #ifdefs in the definitions are quite irritating but |
24 | necessary if we want to avoid duplicating the information. There |
25 | are three different modes: |
26 | |
27 | - PROCINFO_DECL is defined. This means we are only interested in |
28 | declarations. |
29 | |
30 | - PROCINFO_DECL is not defined: |
31 | |
32 | + if SHARED is defined the file is included in an array |
33 | initializer. The .element = { ... } syntax is needed. |
34 | |
35 | + if SHARED is not defined a normal array initialization is |
36 | needed. |
