m4: crypt_xxpg6.m4: Define _DEFAULT_SOURCE for current glibc
|
|
|
|
Current glibc no longer implements the CRYPT extension, so it does not
|
|
declare crypt in <unistd.h> in strict standard modes. The check
|
|
defines _XOPEN_SOURCE, which enables one of these modes. Defining
|
|
_DEFAULT_SOURCE as well again makes available the crypt function
|
|
prototype.
|
|
|
|
This avoids a configure check result change with compilers which do
|
|
not support implicit function declarations.
|
|
|
|
Submitted upstream: <https://github.com/dovecot/core/pull/193>
