Actually this is a continuing source of problems. Linux probably uses
GNU getopt, which has different specs than the SYSV one.
I may have to add a copy of a royalty-free getopt.c as a permanent
part of the distribution -- probably renaming the function to avoid
conflicts with library functions of the same name.
