According to Fergus on 4/15/2009 7:15 AM:

Because dlsym() allows one to have true dynamic dependencies, rather than
static dependencies on .dlls as recorded in the .exe.  The difference is
that a static .dll dependency makes the entire app to fail to load (if you
start the app from a cmd window, you'll get a popup box from the OS about
a missing dependency), whereas dlsym() allows the application to choose
how to gracefully handle load failures (rxvt chooses to tell you about the
missing dependency and exit, but at least rxvt was run by the OS).
