 I am trying to compile tor-0.2.8.2-alpha under Solaris 10 with gcc and I'm
 getting an" Undefined symbol error" for  "signbit" in
 src/common/libor.a(util.o)

                  from ./src/common/crypto.h:17,

 I had no issues compiling and running tor-0.2.7.6 on this system.

 Any help is appreciated.

 Thanks.

 Rainer
