Runtime Token Expansion - some clarification

I recently came across a mail exchange where the following runtime linker error message was observed: illegal mode: potential multiple path expansion requires RTLD_FIRST The exchange, and a quick review of the documents, reveal that some explanation wouldn't go amiss.

A shared library, built from Sun Studio 10 with debugging (-g), was taking 20 minutes to link on Solaris. By comparison, the same link took 4-5 minutes on Linux, and 15 seconds on Windows.
