I have a sneakier idea to avoid the warning. The yy_fatal_error routine
is defined as
(void) fprintf( stderr, "%s\n", msg );
exit( YY_EXIT_FAILURE );
and this is the only use of fprintf in the scan.c file. How about
leaving yy_fatal_error as the error subroutine, and insert
#define fprintf(file,fmt,msg) elog(FATAL, "%s", (msg))
