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, | |
