[exim] warnings during compilation

Hello,

I am compiling exim on a tru64 unix

I have some warnings:

cc -c -O -I.   -I/usr/local/include/openssl/ -I/usr/local/include exim.c
cc: Warning: exim.c, line 3461: In this statement, the referenced type 
of the pointer value "&size" is "unsigned lo
ng", which is not compatible with "int". (ptrmismatch)
  if (getpeername(0, (struct sockaddr *)(&inetd_sock), &size) == 0)
-------------------------------------------------------^
cc: Warning: exim.c, line 3469: In this statement, the referenced type 
of the pointer value "&size" is "unsigned lo
ng", which is not compatible with "int". (ptrmismatch)
      if (getsockname(0, (struct sockaddr *)(&interface_sock), &size) == 0)
---------------------------------------------------------------^

should I worry about this warnings or not ?

thank you in advance
