I say change it for Unix compatibility.  If a path starts with
a slash, chdir should check whether the first directory is a letter
followed by a colon.  If so, it switches drives, else it changes
relative to the current drive.

If we put the above version of chdir under an #ifdef _POSIX_SOURCE
directive, and the DOS style chdir under #else, that would increase
portability for Unix programs while leaving DOS-based programs
alone.
