conflicting types for 'g_value_get_variant'

Hi,
compiling lablgtk-2.14.1 :

+ gcc ...... ml_gobject.c

ml_gobject.c:292: error: conflicting types for 'g_value_get_variant'
/usr/include/glib-2.0/gobject/gvaluetypes.h:230: note: previous declaration of 
'g_value_get_variant' was here

ml_gobject.c:380: error: conflicting types for 'g_value_set_variant'
/usr/include/glib-2.0/gobject/gvaluetypes.h:226: note: previous declaration of 
'g_value_set_variant' was here

if I rename g_value_get_variant()  and  g_value_set_variant() in ml_gobject.c 
(and appropriatly in src/gobject.ml) the compilation succeeds)


The file "/usr/include/glib-2.0/gobject/gvaluetypes.h" belongs to:
libglib2.0-devel-2.25.13-1mdv2011.0
