On some platforms (HP-UX 10.20, SunOS 4.1.4, Solaris 2.5.1), mkstemp has a silly
limit that it can create no more than 26 files from a given template. On
OSF/1 4.0f, it can create only 32 files per process.
+@item
+On platforms where @code{off_t} is a 32-bit type, @code{mkstemp} may not work
+correctly to create files larger than 2 GB. (Cf. @code{AC_SYS_LARGEFILE}.)
+@item
+On some older platforms, @code{mkstemp} can create a world or group
+writable or readable file, if you haven't set the process umask to
+077. This is a security risk.
