I think this should be:
return do_config_from_file(fn, "file", "<stdin>", NULL, stdin, data);
ie. <stdin> is not a separate type, but a file that does not exist in
the filesystem and, thus, has no name. (what you use internally is a
separate issue, but <file,NULL> works for me.)
Also, I'm so used to '<stdin>' as the 'name' (token/handle) of that
file, that it looks very odd spelt otherwise. :-D

So, this looks odd. Using the above would give:
fatal: bad config line 1 in file <stdin>
