There are platforms in which failing to do so causes crashes because of 32-vs-64-bit issues. Not sure if this explains your Windows issue too, but in any case the above is wrong. > myext.o: myext.c > clean: > rm -f myext.o BTW, these rules are unnecessary --- having listed myext.o in OBJS is sufficient. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
