RFD: remove(3)

[Corinna Vinschen]

The remove(3) call in newlib is implemented as a simple call to unlink(2).

SUSv2/Linux/OpenBSD on the other hand define remove(3) as follows:

  If path does not name a directory, remove(path) is equivalent to unlink(path). 
  If path names a directory, remove(path) is equivalent to rmdir(path).

I would plead to implement our own remove(3) call, overriding the newlib
implementation. AFAICS, we can't change the newlib implementation because
newlib doesn't know of rmdir(2) at all.

Thoughts?
