BTW, do you have this warning too?
[WRC] obj-i386\dll\win32\comdlg32\rsrc.coff
windres: warning: 5: "CHOOSE_FONT": 1026: duplicate value
windres: warning: 5: "CHOOSE_COLOR-?n": 1026: duplicate value
It seems it happens into cdlg_Bg.rc
This should be corrected now in r27614.
Somehow duplicate data got into this resource file...
Best regards,
Colin
