It's the same way that (for example) 'pr -e' works: if there's no string immediately after the -e, then no option-argument was specified. In your example, -d has no option-argument and -X is another option, which happens to be invalid. > The bug, IMHO, is in the use of getopt, that departs from POSIX' > specifications for the function, There's no bug here, as GNU m4 builds and runs on BSD, and conforms to POSIX in this area. > "Embrace and Extend" :-/ This nontechnical namecalling is unworthy of you, and does not help the discussion in any way.
