It looks like when we changed regress/GNUmakefile to pull rules from Makefile.shlib, cygwin got broken in the process.
The problem is that regess.dll ends up being a symlink back to itself, because we do a: $(NAME)$(DLSUFFIX): $(shlib) rm -f $(NAME)$(DLSUFFIX) $(LN_S) $(shlib) $(NAME)$(DLSUFFIX) And from Makefile.shlib (for cygwin) ifeq ($(PORTNAME), cygwin) shlib = $(NAME)$(DLSUFFIX) Thus regress.dll gets unhappy :-( I don't know enough about the rest of the way the cygwin port is put together, but it seems that the other platforms all have shlib=lib$(NAME)... -rocco ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
