Hi Balaji,

any chance to get this fixed?  Bootstrap on FreeBSD has now been broken for
some two weeks overall and I hope there aren't other things hidden behind
this one.


Hi Gerald,
	I tried to remove the -ldl flag, but it is giving me errors like this:

/b-trunk-gcc/x86_64-unknown-linux-gnu/./libcilkrts/.libs/libcilkrts.so: undefined reference to `dladdr'
/b-trunk-gcc/x86_64-unknown-linux-gnu/./libcilkrts/.libs/libcilkrts.so: undefined reference to `dlopen'
/b-trunk-gcc/x86_64-unknown-linux-gnu/./libcilkrts/.libs/libcilkrts.so: undefined reference to `dlclose'

	Do you have any suggestions about how to fix them?

Are you linking with -nostdlib or something similar? IIRC thoseroutines are provided by libc on *bsd*. On other systems you may needto link in libdl via -ldl.

I'm sure there's autoconf bits to test whether or not -ldl should beused for any given system.
