Let me elaborate: when _USE_LFN is (bool) FALSE, findfirst() and findnext()
use exactly the same code as _dos_findfirst() and _dos_findnext(). So
applying here the 'reuse code when you can' paradigm leads directly to let
the former functions call the latter when _USE_LFN is FALSE.

Ok, so libc/dos/dir for the low-level wrapper functions.

Ok, dir.h for their declarations.

Ok, then with only one starting underscore ? dos.h header file ?

What do you call external function, given that everything is external to a
certain extent with the 'one function per file' rule ?
Is __doserr_to_errno() external for example ?
