AqBanking

I can't get 6.7.0beta (git-describe calls it 5.6.10-1812-g1b2a3b2c) to build at all:

make[8]: Entering directory '/crypt/space/home/laforge/projects/git/aqbanking/src/libs/plugins/backends/aqhbci/admjobs'

      |       ^~~~~~~~~~~~~~~~~~~~~~~~~~~
      |       AB_Transaction_SetTaxes
make[8]: *** [Makefile:573: jobvpp.lo] Error 1

and indeed, it seems this function is only ever called but not declared/defined anywhere:

$ git grep AB_Transaction_SetVopResult
src/libs/plugins/backends/aqhbci/admjobs/jobvpp.c:      AB_Transaction_SetVopResult(t, sResultString);

It looks like some code is needed but wasn't merged to master before making the tag?

I wanted to build 6.7.0beta, try it (particularly with the VOP opt-out / HKVOO) and report how far I get with Deutsche Bank
