+From 24487a7fa64bfa92bea21be3ca8c155e5de7438f Mon Sep 17 00:00:00 2001
+From: Theodore Ts'o <tytso@mit.edu>
+Date: Fri, 29 Jan 2021 22:28:31 -0500
+Subject: configure.ac: fix build failure on systems with pthreads && !fuse
+ support
+
+The configure script checks for pthread.h as part of double-checking
+that the FUSE support works correctly, which implicitly defined
+HAVE_PHREAD_H.  If the FUSE libraries are not present (or fuse support
+is explicitly disabled), this check doesn't happen and so
+HAVE_PTHREAD_H is not defined, and this causes a build failure.
