call to undeclared function ‘waitpid’; ISO C99 and later do not support implicit function declarations.

This can occur after doing a cleanup and rebuilding from scratch. It seems that waitpid() has not been properly included. Edit the file linux/flutter/ephemeral/.plugin_symlinks/flutter_pty/src/flutter_pty_unix.c to add the following lines at line number 10.

#include <sys/types.h>
#include <sys/wait.h>
