Hi,
I found an anomaly on the translations page. Whenever the Makefile shows a generic rc file (last one added for RC_SRCS) the language before that shows warnings on the page. Example:
http://source.winehq.org/transl/lang.php?lang=004%3A01
zh (Chinese (Traditional)) shows up most of the warning as the entries in the Makefile are sorted.
Not sure yet, if this is an issue with wrc or transl.
