 Hi,

 "cdrtools" fails to build on MacOS Monterey with ARM64, with the following
 error:

 {{{
 :info:build     ==> COMPILING "getav0.o"
 :info:build In file included from getav0.c:25:
 :info:build In file included from ../include/schily/avoffset.h:54:
 :info:build ../incs/arm64-darwin-clang/avoffset.h:17:2: error:
 unterminated conditional directive
 :info:build #ifndef __AVOFFSET_H
 :info:build  ^
 :info:build 1 error generated.
 :info:build smake: Operation not permitted. *** Code 1 from command line
 for target 'getav0.o'.
 }}}

 I will attach the build log now ...
