Can you please tell me how to reproduce that hell in libgettextpo?
I tried the patch below, and so far it seems to work reasonably well.
You lose the ability to do 'make clean' in either of
gettext-tools/libgettextpo and gettext-tools/src without also cleaning
the other, and some object files of the former live in the latter and
have long names, but that's about it. What am I missing?
(The renaming trick is documented in the Automake manual.)
Thanks,
