Error in compilation with function crypt( )

[Santosh Singh <sanhackin@xxxxxxxxx>]

Hi
  anyone can help me when I tried to compile a program
using function crypt(), encrypt() defined in unistd.h
I am not getting it. As it is defined as extern
function. I have also tried with gcc -O option but
helpless. I have also included crypt.h but again same
error. Using grep I found crypt( ) in unistd.h and
crypt.h. Plz help me.
 Santosh
