+	* fixinc/fixfixes.c (main) [__MSDOS__]: Avoid overwriting the
+	output file with the temporary one by appending ".X" to generate

+	extension, replace it with ".X".

+	not $DESTDIR, to find applyfix.  Use sprintf instead of snprintf;
+	reallocate the command buffer while copying the command-line
+	argument.  Redirect the output directly to the temporary file,

+	expects.
+
+	* fixinc/fixincl.sh: Export ORIGDIR.  If $DJDIR is set in the

+	directory.  When cleaning up the DONE files, look for them
+	case-insensitively.  Don't try to remove symlinks if they aren't
+	there.
+
+	* fixinc/fixlib.c (make_raw_shell_str): Accept new argument smax;
+	all callers changed.  Declare pz "const char *", to avoid compiler
+	warnings.
+
+	* fixinc/fixlib.h (ENV_TABLE): Get ORIGDIR from the environment.

-	limits are satisfied.  Throttle from currfn_max_inline_insns, not from

-	* fixinc/fixfixes.c (main) [__MSDOS__]: Avoid overwriting the

-	extension, replace it with ".X".

-	not $DESTDIR, to find applyfix.  Use sprintf instead of snprintf;
-	reallocate the command buffer while copying the command-line
-	argument.  Redirect the output directly to the temporary file,
-	instead of going through another temporary file.
-	(process): Close the temporary file before unlinking it.

-	expects.
-
-	* fixinc/fixincl.sh: Export ORIGDIR.  If $DJDIR is set in the

-	directory.  When cleaning up the DONE files, look for them
-	case-insensitively.  Don't try to remove symlinks if they aren't
-	there.
-
-	* fixinc/fixlib.c (make_raw_shell_str): Accept new argument smax;
-	all callers changed.  Declare pz "const char *", to avoid compiler
-	warnings.
