+ Syntax errors in libtiff: replace compat lib by native OS version
+ add LIBS = -lm in tcl8.6/unix/configure for openSUSE Tumbleweed
+ Need to use pragma once in an awk script (broken guard) for openSUSE Tumbleweed
+ replaced config.{guess|sub} to support aarch64 and PPC
+ added BUILT_SOURCES in two Makefile.ac to avoid rat races with parallel build
- Version derived from ds9.si.edu 8.2.1
- Version derived from ds9.si.edu 8.1b2
+ Employing https://core.tcl-lang.org/tcltls/ = TLS 1.7 to replace
the variant within sources so openSSL 1.1 systems can be handled.
Detail: the original ds9 source code is here as ds9.8.1b2.tar.gz
and the TLS 1.7 code in tcltls-1.7.19.tar.gz . The RPM spec-file
merges the newer TLS into the unbundled ds9 directories.
+ Patched various non-void functions which may (virtually) fall
through switch-cases and not return a value, so gcc reports warnings.

please the build.opensuse.org service and not needed with a rpmbuild.)
