| * When building position independent code with GCC using the -fPIC option, |

| * building a dynamic object (either a shared library or an executable) that |
| * may have symbol references that can only be resolved at load time. For a |
| * variety of reasons (ELF symbol preemption, the CoW footprint of the section |
| * that is modified by the loader), this results in all references to symbols |
| * with external linkage to go via entries in the Global Offset Table (GOT), |
| * which carries absolute addresses which need to be fixed up when the |
| * executable image is loaded at an offset which is different from its link |
| * time offset. |
| * |
| * Fortunately, there is a way to inform the compiler that such symbol |
| * references will be satisfied at link time rather than at load time, by |
| * giving them 'hidden' visibility. |
