+/* why this routine ?
+ Problem: link attack
+ Bad user wants to overwrite a file (mywork.txt) of good user.
+ File permissions of mywork.txt is 700 so that bad user can not
+ change or overwrite the file. Directory permissions allow bad user
+ to write into directory. Bad user sets symlink from a file that good
+ user will write soon (image.pnm) to mywork.txt.
+ ==> Good user overwrites his own file, he is allowed to do so.
+
+ Solution: remove file.
+ Create outputfile and make sure that it does not exist while creation.
+
+ The file is created with the requested image-file permissions.
+
+ Note: This case is a bit curious because it is only a small part of a larger problem:
+ When other users have write access to the directory they simply can move
+ mywork.txt to image.pnm. If they do it in the right moment the file is
+ overwritten without any notice of good user. If they do it long before xsane
+ wants to write image.pnm then xsane will possibly ask if image.pnm shall be
+ overwritten. So the real solution is to make the direcoty permissions safe!!!
+ But some users asked for this and so I added this.
+
+
+ This routine shall not be called for temporary files because temp files shall not
+ be removed after they have been created safe. (Although a temporary file should
+ not be a symlink so there should be no problem with this)
