Thank you, Gaius.

It is indeed a GNUism and part of GNU core-utils.  (There is a POSIX 
realpath() function.)
NetBSD installs it as grealpath.  I modified the calcpath script to call 
grealpath.

But now I have a subsequent build problem:

gmake[3]: *** [../../../src/gcc-git/gcc/m2/Make-lang.in:1204:

The file gcc/m2/config.log aprubtly ends "configure: exit 77" with no 
indication of what it tried to compile.

Sincerely,
