+/* lstat works differently on Linux and Solaris systems. POSIX (see

+ has the desired semantics (in treating `lstat("symlink/",sbuf)' just like
+ `lstat("symlink/.",sbuf)', but on Solaris it does not.
+
+ If FILE has a trailing slash and specifies a symbolic link,
+ then append a `.' to FILE and call lstat a second time. */
