the missing prototypes are in the generated header:

$ grep yy.*_col parse_lex.h 
#define yycolumn (YY_CURRENT_BUFFER_LVALUE->yy_bs_column)
    int yy_bs_column; /**< The column count. */
int priv_gst_parse_yyget_column  (yyscan_t yyscanner );
void priv_gst_parse_yyset_column (int column_no ,yyscan_t yyscanner );


But lex.priv_gst_parse_yy.c does not include it:
$ grep parse_lex lex.priv_gst_parse_yy.c 
$

instead flex already weaves it in:
$ grep -n yyget_col *.c 
lex.priv_gst_parse_yy.c:1019:int priv_gst_parse_yyget_column  (yyscan_t
yyscanner );
lex.priv_gst_parse_yy.c:2189:int priv_gst_parse_yyget_column  (yyscan_t
yyscanner)

what version of flex do you have?
$ flex -V
flex 2.5.35

if i include parse_lex.h in parse.l, gcc complains later.

if we get [-Werror=redundant-decls] out of the make, than we can include
parse_lex.h in parse.l
