Hi Kamil,

Thanks a lot for testing this!

Yes - it applies on top of the handful simple fixes in my simple180
branch, which I posted before. Sorry, should have made that more clear.

Good find - I believe libgcrypt was actually successfully detected by
the tests, but the end logic needs a little fixing. Patch attached.

Oh! How did you notice that it does not take effect, and how did you
deal with that instead, if you need it?

The --with-x-prefix options are a bit unrelated; they are created and
supposed to be handled by AC_LIB_HAVE_LINKFLAGS, but they are related
because they deal with library finding, so I'd like to know more
about the problem you found. If you have config.log from a problem
run maybe you can send it to me. (Maybe off-list if it's large.)

Thanks again
