+ * Aix' own version of dladdr().
+ * This function tries to mimick dladdr(3) on Linux
+ * (see http://linux.die.net/man/3/dladdr)
+ * dladdr(3) is not POSIX but a GNU extension, and is not available on AIX.
+ *
+ * Differences between AIX dladdr and Linux dladdr:
+ *
+ * 1) Dl_info.dli_fbase: can never work, is disabled.
+ *   A loaded image on AIX is divided in multiple segments, at least two
+ *   (text and data) but potentially also far more. This is because the loader may
+ *   load each member into an own segment, as for instance happens with the libC.a
+ * 2) Dl_info.dli_sname: This only works for code symbols (functions); for data, a
+ *   zero-length string is returned ("").
+ * 3) Dl_info.dli_saddr: For code, this will return the entry point of the function,
+ *   not the function descriptor.
