[Refdb-users] refdb installation problem

[<Hon...@gs...>]

Dear Sir/Madam,

I download refdb-0.8.0.tar.gz and want to install it in my Unix 
workstation (the system is sparc-sun-solaris2.8).
when I compile the source file, I got the following error message:
          refdbd.c: 145: '__sighandler_t' undeclared 

Would you give me some advice what is wrong with it please? 
Thank you very much for your kindly attention.
