mktemp possibly used unsafely

[jungle-boogie]

While researching issue #85, came across this during a build:

/tmp/mlr_test_util-19aa81.o: In functionwrite_temp_file_or_die':
lib/mlr_test_util.c:(.text+0x24): warning: warning: mktemp() possibly used unsafely; consider using mkstemp()

Thanks.

The last two are due to missing single quotes on your shell commands.

I'm sure there's a system-dependent regression here but I'm skeptical that your bisection has identified the culprit commit. In a couple days I'll get you some experiments to run if you don't mind.

Also I need to set up a FreeBSD VM or something to shorten these cross-platform debug cycles.
