-Subject: [PATCH] auth-pam.c: add missing include limits.h
-
-On most systems limits.h is pulled in by some other header and thus no
-error is ever triggered, but it's possible to find the right environment
-which lackis this and prevents compiling auth-pam.c (possibly when using
-LibreSSL).
-
-Include the header explicitly as it includes the definition of PATH_MAX.
-
-(note that this bug is fixed in Gentoo since 2020 by including a custom
-patch, but apparently the issue was never reported upstream)
