I have update the latest glib and pango.
glib 2.20.5-1 -> glib_2.22.2-1
pango_1.24.5-2 -> pango_1.26.0-1

Results went worse :-(.

Please see

Script
***********
set term pngcairo
set title 'Title'
set out 'testpngcairo_ChangeLog20091106_2.png'
plot sin(x)
set out

Screen output

0029 testpngcairo_ChangeLog20091106.png *** previous one on win32
0030 testpngcairo_ChangeLog20091106_2.png  *** this time  on win32
0031 testpngcairo_ChangeLog20091106_cyg.png *** this time on cygwin
0032 wxt_ChangeLog20091106.png **** this time for wxt term on win32

As is seen in testpngcairo_ChangeLog20091106_2.png, plot area is full of screen and all labels seem to
be out of plot area.

This is also seen at the wxt terminal as is seen in wxt_ChangeLog20091106.png.

Terminal type set to 'wxt'
gnuplot> plot sin(x)
Fontconfig error: Cannot load default config file

Perhaps the latest pango (also glib ) libraries are too new for the  fontconfig-dev_2.7.3-1 (and also
for freetype_2.3.9-1, libpng_1.2.39-1)

My version list at present
glib_2.22.2-1
pango_1.26.0-1
cairo_1.8.8-2
fontconfig_2.7.3-1
freetype_2.3.9-1

Please tell me your version list that you have used this time change.

Tatsuro
