Read doc/posix-functions/realpath.texi:

mingw and BeOs lack it.  mingw is a far cry from unix-like, but a
widely-used porting platform.  BeOs is Unix-like, but these days, you
are more likely to see people porting to Haiku instead, and Haiku has
added realpath().

More telling is the fact that Solaris realpath() is buggy (it fails to
allocate on a NULL argument, and fails to give an absolute answer for a
relative query).

Try canonicalize-lgpl instead; much lighter-weight, and is the only
module that gives you a working realpath().

canonicalize no longer even provides realpath().  But again,
realpath.texi tells you to use canonicalize-lgpl rather than canonicalize.
