[gnome-db] problem on enums compiling libgda on mingw/msys under windows

libgda version 4.1.3

gda-enum-types.h, and other glib-mkenums generated files, look like this

G_BEGIN_DECLS
C:/msys/1.0/* enumerations from "gda-config.h" *//n
GType gda_config_error_get_type (void);
#define GDA_TYPE_CONFIG_ERROR (gda_config_error_get_type())
C:/msys/1.0/* enumerations from "gda-connection-event.h" *//n
GType gda_connection_event_type_get_type (void);
#define GDA_TYPE_CONNECTION_EVENT_TYPE (gda_connection_event_type_get_type())
GType gda_connection_event_code_get_type (void);
#define GDA_TYPE_CONNECTION_EVENT_CODE (gda_connection_event_code_get_type())
C:/msys/1.0/* enumerations from "gda-connection.h" *//n
GType gda_connection_error_get_type (void);
#define GDA_TYPE_CONNECTION_ERROR (gda_connection_error_get_type())
GType gda_connection_options_get_type (void);
#define GDA_TYPE_CONNECTION_OPTIONS (gda_connection_options_get_type())
...

i think it is a problem of mingw/msys, because there's similar issue  
on using xml-catalog
