D.gnu - getcwd from file.d under AIX

First let me thank David Friedman for the AIX port of gdc.

I have encountered a minor problem in the phobos library on AIX. AIX 
doesn't allow the size  parameter to be 0 for getcwd, it returns an 
EINVAL error.

Currently file.d contains the line
	
	p = unix.getcwd(null, 0);

For my own needs I have just hacked this to replace 0 by 1024,  but it 
probably should be a loop (pardon my limited D)

   for (bsz = 1024; (p = unix.getcwd(0, bsz)) == null; bsz += 1024) {
     if (getErrno() != ERANGE)
       break;
   }

current path is > 1024.

for (....) {
  if (...)
     break;
  free(p);
}
