If they conform to C89 there should be no problem. In C89, returning

For example (reading the comments that you made earlier, perhaps you
should learn something old about C89):
In that case, it sounds like we should suggest to people that they use
the POSIX environment rather than try to port to a C-only environment.
But I am surprised that a C-only environment would mess up in this
way, even on mainframes.
VMS, where an application can return EXIT_SUCCESS or EXIT_FAILURE from
main - but (still complying with C89), those are not 0 and 1 respectively.
