I don’t think this is the same problem. Using the latest master for both
GRUB and flex I get this error (but not with flex 2.6.3):

  grub_script.yy.c: In function ‘yy_fatal_error’:
  grub_script.yy.c:19:22: error: statement with no effect [-Werror=unused-value]
   #define fprintf(...) 0
                        ^
  grub_script.yy.c:2367:2: note: in expansion of macro ‘fprintf’
    fprintf( stderr, "%s\n", msg );
    ^~~~~~~

Configuring with --disable-werror works. The relevant commit is
