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.

There's no bug here, as GNU m4 builds and runs on BSD, and conforms to
POSIX in this area.

This nontechnical namecalling is unworthy of you, and does not help
the discussion in any way.
