That seems to be the case indeed, Rene (in CC:) found a similar issue with libreoffice. See #1133694 and https://savannah.gnu.org/support/index.php?110879 I just verified that movit builds correctly with GCC 16 if I specify -std=gnu++17 with DEB_CXXFLAGS_APPEND=-std=gnu++17. Similarly, GCC 16 has no problem building the package with autoconf 2.73-1 from experimental.
