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