Subject: Have rename() semantics changed?

Hi,

The latest cygwin seems not to allow open files to be renamed. This
works under Unix. It is not normally allowed under Windows, but worked
in previous versions of the cygwin environment.

Is this an official change, or could it be a bug?

I noticed this because it broke the OOC Oberon-2 compiler
(ooc.sourgeforge.net) under cygwin. The following code snippet
demonstrates the problem.

#include <stdio.h>

char * oldName = "test.file^";
char * newName = "test.file";

int main(int argc, char ** argv) {
	int result;
	FILE * f = fopen(oldName, "w");

	result = rename(oldName, newName);
	if (result != 0) {
		perror("Rename");
	} else {
		printf("OK!");
	}
	fclose(f);
}

The latest cygwin (1.1.2) now returns an error 13 (permission denied).

Cheers,
  - Stewart
