Sorry to disagree: We have, e.g., NO_MMAP, and I can set it to request
that some alternative is used, even if I have a working mmap(). The option
name "NO_GETTEXT" is in exactly the same spirit.

Just like we go through _() in C code, even though there may be an
implementation that does not do i18n at all, right?

gettext/eval_gettext annotations are the shell equivalent of _()
annotations in C code, aren't they? Neither go away just by defining
NO_GETTEXT. It is just a quality-of-implementation issue that those
annotations have as little overhead as possible if NO_GETTEXT is defined.
In C, it is easy, in shell code it may be more involved.
