Hi,

While running your changed tests, I think I found new failures.
Being a bot and all I'm not very good at pattern recognition, so I might be
wrong, but could you please double-check?

Full results can be found at:

Your paranoid android.

AX_COMPARE_VERSION is not part of the standard autoconf macros. This
breaks the build for me:

configure:4595: error: possibly undefined macro: AC_MSG_RESULT
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
