mac test failures on gtk3 branch

[Jeremy Lavergne]

Hi guys,

Following the recent gtk3 conversations, I got that branch going on the Mac 
again.

There are three classes of test failures to point out; config.log and 
testsuite.dir/log attached.

481, 482, 483, 484 stdout:
these failures can be ignored regarding CGFontGetGlyphPath deprecation warnings.

481, 484 segfault (I can provide more if you can remind me the process for 
firing up a pspp test in a debugger):
+/opt/pspp/var/macports/build/_Users_aeetes_dports_math_pspp-devel/pspp-devel/work/pspp-0.8.4-g68aeca/tests/testsuite.dir/at-groups/484/test-source:
 line 43: 84764 Segmentation fault: 11  pspp -o pspp.pdf scatter.sps

497, 1019, 1022 stdout:
these tests fail around just two distinct Pango-WARNING patterns:
+(process:96432): Pango-WARNING **: Invalid UTF-8 string passed to 
pango_layout_set_text()
+(process:96432): Pango-WARNING **: shaping failure, expect ugly output.
