* and error state.
* The above changes should take care of a problem initially reported
* by "Steven J. Hill" <sjhill@realitydiluted.com>.
+ *
+ * 8-25-2002
+ * Changed fclose behavior when custom streams were enabled. Previously,
+ * the cookie pointer was set to NULL as a debugging aid. However,
+ * some of the perl 5.8 test rely on being able to close stderr and
+ * still try writing to it. So now, the cookie pointer and handler
+ * function pointers are set to that it is a "normal" file with a
+ * file descriptor of -1. Note: The cookie pointer is reset to NULL
+ * if the FILE struct is free'd by fclose.
