Noteworthy changes in release 2.6.8 (2026-11-11) [stable]

build

• Flex now builds when configured with --disable-nls. It failed to
  compile with a compiler that treats a call to an undeclared function
  as an error, because the report of backing-up states used a function
  that is only declared when translations are enabled. (#844)

  Thanks to Hendrik Donner.
