BE		 8/* libxcrypt is a replacement for glibc's libcrypt, and libcrypt might be
9 * removed from glibc at some point. As part of the removal, defines for
10 * crypt(3) are dropped from unistd.h, and we must include crypt.h instead.
11 *
12 * Newer versions of glibc (v2.0+) already ship crypt.h with a definition
13 * of crypt(3) as well, so we simply include it if it is present. MariaDB,
14 * MySQL, PostgreSQL, Perl and some other wide-spread packages do it the
15 * same way since ages without any problems.
