You resolve the conflict by editing the file, removing the markers and the erroneous line. Suppose you end up with this file:
#include <stdlib.h>
#include <stdio.h>
int main(int argc,
char **argv)
{
init_scanner();
parse();
if (argc != 1)
{
fprintf(stderr, "tc: No args expected.\n");
exit(1);
}
if (nerr == 0)
gencode();
else
fprintf(stderr, "No code generated.\n");
exit(nerr == 0 ? EXIT_SUCCESS : EXIT_FAILURE);
}
