Hi
attached is a small patch to include package iftex to latex exports. Since
we support several
compilers, it is useful to have this package to detect the compiler in
included latex files.
Best, /PA

May you please explain why it is necessary to include iftex in _all_
latex exports? AFAIK, none of the commands provided by this package are
used by ox-latex.

We generally do not add packages unless they are strictly necessary for
the export.
Also, iftex is not compatible with scrbase, so the proposed change can
be harmful.
