Description: When _XOPEN_SOURCE is defined, the subsequent #include <unistd.h>
will define a correct function prototype for the crypt function. This avoids
segfaults on architectures where the size of a pointer is greater than the size
of an integer (ia64 and amd64 are examples). This may be detected by looking
for build log lines such as the following:
auth_shadow.c:183: warning: implicit declaration of function ‘crypt’
auth_shadow.c:183: warning: cast to pointer from integer of different size
