yes, I also tried that to verify whether or not I needed a work-around
for gets, though using
"xit(int s){ exit(s);}"
was easier to toggle in and out of the test program by removing or
adding the 'e' before 'exit' calls in the program.
Also simply adding:
extern int exit(int);
was another way to *make* it work, if that was what I needed to do
