(define-public libxcrypt-without-failure-tokens
;; This version of libxcrypt is used for guile-2.2.4, which is used in Guix
;; v1.0.0 and thus needs to be supported for guix time-machine.
;;
;; Guile uses the 'crypt' hashing function that used to be provided by glibc,
;; but was moved to libxcrypt around glibc 2.39. However, the crypt function
;; in libxcrypt works differently for invalid salt values: libxcrypt returnns
;; the failure token "*0" for (crypt "pass" "$X$abc"), where glibc raised
;; "Invalid argument" (EINVAL). The --disable-failure-tokens flag lets
;; libxcrypt behave in the same way as glibc.
;;
;; Guile 2.2.4 explicitly checks for the glibc behavior of crypt, and thus
;; needs libxcrypt to be compiled with --disable-failure-tokens.
