+Patch taken from Debian sid.
+
+Description: Support uncompressing and compressing soft links.
+ Historically, ncompress for Debian has been built using a command line
+ directly in debian/rules.  For 4.2.4.5-1, I simplified by swtching to the
+ upstream Makefile.  However, that caused a regression - the Debian version of
+ ncompress has always successfully handled soft links, but this stopped
+ working.  To revert to the original behavior, I need to remove -DLSTAT from
+ the build options, to be consistent with how the code was previously built.
