I noticed that lapwing is bleating about
ccache gcc -std=gnu99 -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Werror=vla
-Wendif-labels-Wmissing-format-attribute -Wformat-security -fno-strict-aliasing -fwrapv -fexcess-precision=standard -g

cubescan.c:1689:5: warning: no previous prototype for 'cube_yyget_column' [-Wmissing-prototypes]
cubescan.c:1765:6: warning: no previous prototype for 'cube_yyset_column' [-Wmissing-prototypes]
and likewise in segscan.c. lapwing is using flex 2.5.35, so probably
this is the same bug worked around in parser/scan.l:
/*
* Work around a bug in flex 2.5.35: it emits a couple of functions that
* it forgets to emit declarations for. Since we use -Wmissing-prototypes,
* this would cause warnings. Providing our own declarations should be
* harmless even when the bug gets fixed.
*/
extern int core_yyget_column(yyscan_t yyscanner);
extern void core_yyset_column(int column_no, yyscan_t yyscanner);
