That figures. Small wonder I have so much respect for M$.

Of course d_type is a critical element.

It seems that stat(2) may also have system dependencies, for example does
st_mode provide S_ISREG indication.
If one ignores M$, would opendir, readdir (just to get file names) and stat(2)
be a more reasonable route?
The most critical element with this basic method is to get the damn file
names. Otherwise a preoperation with a shell program of some sort and an
ancillary program is required to create a special file.
Probably could get by without mode detection and just open the file and scream
if it doesn't open or read properly.
OK, let's just worry about opendir and readdir and do the rest by brute force.
Thanks for your comments.
