with glibc's libcrypt.  It comes with a set of extended interfaces
pioneered by Openwall Linux, crypt_rn, crypt_ra, crypt_gensalt,
crypt_gensalt_rn, and crypt_gensalt_ra.  Also, programs that use
certain legacy APIs supplied by glibc's libcrypt (encrypt, encrypt_r,
setkey, setkey_r, and fcrypt) cannot be compiled against libxcrypt.

I think it would make more sense to add the new APIs to glibc, without
dropping existing APIs or changing the implementation of the remaining
existing APIs.

I disagree, and I think so do all the people who work on glibc.
