I don't know, and can't easily test. However, I had seen the same
pattern be used elsewhere, for example:
$ git grep dev/null -- libstdc++-v3/testsuite/lib/
libstdc++-v3/testsuite/lib/libstdc++.exp: set lines
[v3_target_compile $src /dev/null executable ""]
[several more]
..., so assumed that to be OK.
Now that I'm reading [dejagnu]/target.exp:default_target_compile, I see
that for "[is_remote host]", it *always* passes "-o a.out" and then
"remote_upload host a.out $destfile", so "/dev/null" never escapes from
the system that DejaGnu/runtest is running on, which is always a POSIX
system as far as I know.
Otherwise, we could easily switch all these to a temporary output file,
which is then deleted right away...
