Trouble compiling Procmail-3.10 on BSDI

Hi,

I am getting following message on compiling Procmail-3.10 under BSD:

cc -c -O formail.c
formail.c:38: `daemon' redeclared as different kind of symbol
/usr/include/stdlib.h:136: previous declaration of `daemon'
formail.c:38: warning: `daemon' was declared `extern' and later `static'
*** Error code 1
 
Stop.
*** Error code 1
 
Stop.


What modifications should I do to get it compiled.

Thanks.
Anu
