From ab1a11be7858e1f92ee2e4ee1d70fabe7d5fe0ee Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Mon, 7 Feb 2011 21:54:01 +0100 Subject: [PATCH] mingw_rmdir: set errno=ENOTEMPTY when appropriate On Windows, EACCES overrules ENOTEMPTY when calling rmdir(). But if the directory is busy, we only want to retry deleting the directory if it is empty, so test specifically for that case and set ENOTEMPTY rather than EACCES. Noticed by Greg Hazel.
