Comment (by crow):

 I tried bisect but there were two commits which could not be build here so
 i skip them. Please not that compile of 12 commits were successful so I
 can only guess it is not the build system.

 bisect
 good n3.2.4
 bad n3.3 and current master as of today

 {{{
 $ git bisect reset
 We are not bisecting.
 $ git bisect start
 $ git bisect good d4b731e271ba944ade8f6a128271479529507de9
 $ git bisect bad 1968a1eef1cae22e162259d7082c2eea98d81e32
 Bisecting: 930 revisions left to test after this (roughly 10 steps)
 [928db5134478b4a410d9256a4d56cd8a7d4989b9] Merge commit
 '27085d1b47c3741cc0fac284c916127c4066d049'
 $
 }}}

 {{{
 $ git bisect skip
 There are only 'skip'ped commits left to test.
 The first bad commit could be any of:
 38efff92f1ef81f3de20ff0460ec7b70c253d714
 4a9bab3db0d9ec449ebc8b5e823374d1d1df7761
 744801989099df26e90b00062c645969c5347533
 We cannot bisect more!
 $
 }}}

 Why this commits were skipped:

 {{{
 38efff92f1ef81f3de20ff0460ec7b70c253d714
 4a9bab3db0d9ec449ebc8b5e823374d1d1df776164
 }}}

 is because i needed to exclude almost half of stuff from '''./configure'''
 and then again there were such compile errors

 Unknown option(s)

 {{{
 --disable-stripping \
 --enable-fontconfig \
 etc etc.
 }}}
