Hello David,

in ups/cx_onefile.c change line 367 from

    if (entry_name != NULL && strcmp(entry_name, "main") == 0) {
to
    if (entry_name != NULL) {

This will allow the function specified by the '-e' option to be a real
alternative entry point, with access to the same parameters as "main", i.e.

    main(argc, argv, envp)
    int argc;
    char **argv, **envp;

Regards,
Ian.
