Here is a gotcha for C programs which will be ported to PRIMOS.

#include <stdio.h>
...
FILE *ifptr = stdin;
...
main(...) {....}

breaks BIND, which crashes with the approximate message
"IOBUF_: Attempt to reference undefined common."

The cure is to initialize FILE pointers with assignment statements, e.g.

#include <stdio.h>
....
FILE *ifptr;
main(...) { ifptr = stdin;....}

I haven't tested it on SEG.

Also, as far as I know, C programs should be compiled using the -oldfortran
option.
