Well, then, who has the right to approve such a patch?

Well, perhaps I wasn't clear enough on what is the problem:

-	case "$<" in \
-	  ./*) ;; \
-	  ../*) \
-	     echo $(LN) $< as$(exeext); \
-	     $(LN) $< as$(exeext) || cp $< as$(exeext) ;; \
-	  *) echo '#!$(SHELL)' > as; echo 'exec $< "$$@"' >> as ; \
-	     chmod +x as ;; \
+	case "$(build)" in \
+	  *mingw32*) \
+	    cp $< as$(exeext) ;; \
+	  *) \
+	    case "$<" in \
+	      ./*) ;; \
+	      ../*) \
+	        echo $(LN) $< as$(exeext); \
+	        $(LN) $< as$(exeext) || cp $< as$(exeext) ;; \
+	      *) echo '#!$(SHELL)' > as; echo 'exec $< "$$@"' >> as ; \
+	        chmod +x as ;; \
+	    esac \

The cases with ./*) and ../*) already well handled, and just kept "as 
is" when $(build) is mingw32. The $(LN) command succeeds, that's not the 
problem.

Only the remaining case, which creates a shell script, fails on mingw32. 
The shell script is spawned to call the assembler, which fails. Only 
real win32 executables can be spawned.
