[Daniel Hartmeier <daniel_(_at_)_benzedrine_(_dot_)_cx>]

While silc-client 0.7.6 did build on macppc (-current as of a couple of
days ago), 0.9 doesn't:

silcsim.c: In function `silc_sim_alloc':
silcsim.c:99: `RTLD_NOW' undeclared (first use in this function)
silcsim.c:99: (Each undeclared identifier is reported only once
silcsim.c:99: for each function it appears in.)
silcsim.c: In function `silc_sim_error':
silcsim.c:152: warning: return discards qualifiers from pointer target type
*** Error code 1
