It is probable this file must be entirely rewritten to match current
Configure. I do not think we ever use the resulting Odos/paricfg.h
anymore.

It seems this is not a problem with stat per se, but with the POSIX
macros S_ISDIR/S_ISREG.
I suppose the MSC documentation of stat should say how st_mode must
be understood.

The point of this code is to check whether something is a directory or a file.
