The Linux man pages say:

DESCRIPTION
       The mktemp() function generates a unique temporary filename
       from template.  The last six characters of template must be
       XXXXXX and these are replaced with a string that makes the
       filename unique.  Since it will be modified, template must not
       be a string constant, but should be declared as a character
       array.

CONFORMING TO
       4.3BSD, POSIX.1-2001.  POSIX.1-2008 removes the specification
       of mktemp().

My POSIX spec is older than 2001 so I can't confirm this.  Note that
the XXXXXX part is *not* a filename component, but a pattern to be
replaced, so the "files are case ignoring" argument doesn't apply.
