| "Unknown identifiers". direct.h defines functions like rmdir, chdir, 
| mkdir, getcwd...

POSIX systems declare rmdir, chdir, and getcwd in unistd.h.  Perhaps
the replacement for unistd.h should include direct.h for MSVC?

POSIX systems declare mkdir in sys/stat.h.  In Octave, all uses of
sys/stat.h go through libocave/statdefs.h, so maybe we could include
direct.h there for MSVC?  I'd prefer to NOT do it this way though:

  #if defined (_MSC_VER)
  #include <direct.h>
  #endif

but instead with some kind of feature test, so that we can write
something like

  #if defined (DIRECT_H_DECLARES_MKDIR)
  #include <direct.h>
  #endif
