WTF?  On my FC4 system at least (with gc-6.5):

$ldd /usr/lib/libgc.so
         linux-gate.so.1 =>  (0x001f2000)
         libpthread.so.0 => /lib/libpthread.so.0 (0x00e8d000)
         libdl.so.2 => /lib/libdl.so.2 (0x00977000)
         libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x004b5000)
         libc.so.6 => /lib/libc.so.6 (0x006ca000)
         /lib/ld-linux.so.2 (0x00433000)

(Not sure what linux-gate.so.1 is??)

I'll have to go check on FC5(devel) to see if libgc really did link 
against libdl/libpthread or not.

Is this failure specific to x86_64 or does it occur on i386 too?
