However, some platforms still are on POSIX.1, so replacing it instead of providing a configure detection/switch for it might cause issues. POSIX.2 is not a newer POSIX version, but rather a book (“Shell and utilities”) in pre-2001 standard revisions, and it has nothing to do with the system interfaces (that is POSIX.1). And the only mention of getpass() in POSIX (at least, since the 2001's edition) indeed seems to be [1], in the list of functions that have not been carried forward from XSH5, the 1997 revision of “System Interfaces and Headers” (that is, SUSv2)[2], where it is inherited from SUSv1[4] from XPG[5] and, as Alejandro already mentioned, marked as obsolete, per XPG3 to XPG4 migration guide[6]; the previous, 1988, version of POSIX[3] does not mention getpass() at all.
