Here's a proposed patch to do that.
I've tested it on GNU/Linux, though not on DOS.

+	Use full name for m4/gnulib-comp.m4, except on DOS.
+	Previously the file was named m4/gl-comp.m4 on all hosts,
+	even though the file's name in gnulib is m4/gnulib-comp.m4.
+	This had a problem when merging from gnulib, as the code temporarily
+	renamed it to the full name, causing problems when interrupted.
+	With this change, the file ordinarily has its full name, except
+	that on DOS it has the shorter name.
+	* m4/gnulib-comp.m4: Rename from m4/gl-comp.m4.
+
 	Make merging from gnulib a script, not a makefile action.
 	Putting it in a makefile has some problems with reflection, as
 	merging from gnulib updates 'configure', which can update the makefile.
