+
+ * exec.c (exec_finish): Show errors when temp files cannot be
+ deleted for whatever reason.
+
+ * exec.c (exec_read): Don't rely on WEXITSTATUS being present.
+
+ * exec.c (make_tempdir): Add temp file creator for win32. Don't
+ create an incoming temp file if the exec is write-only.
+
+ * keyserver.c (keyserver_spawn): Clean up error handling, for when
+ the spawn fails.
+
+ * photoid.c (show_photo): Clean up error handling.
+
+ * misc.c (check_permissions): Neaten.
+
2001-12-25 David Shaw <[email protected]>
* mkdtemp.c (mkdtemp): Add copyleft info and tweak the 'X' counter
