It could happen that Wolfgang is hacking inside the MELT runtime to add
support for loop-s.

Perhaps re-merging the current MELT branch into your private branch
(assuming you have a private MELT variant) might help, because on my
side with GCCMELT_CC set to gcc-4.5 the make log contains


make warmelt1
make[4]: Entering directory `/usr/src/Lang/_MeltBoot/Obj/gcc'
date +"/* empty-file-for-melt.c %c */" > empty-file-for-melt.c-tmp

+01.pic.o ./warmelt-first.0-stamp.c -o warmelt-first.0.so
rm -f ./warmelt-first.0-stamp.c

As you can see, the inner make -f ../../melt-branch/gcc/melt-module.mk
has no -gtoggle inside the GCCMELT_CFLAGS. I see no reason it won't work
with gcc-4.4 as GCCMELT_CC

The GCC MELT was svn checkout cleanly, the svn info is

So I tend to still believe that I did fix that bug, but I am not sure of
that. And I am not able to reproduce that bug on the latest MELT branch
rev 159821

Perhaps you might try to merge again the latest MELT branch into your
private one; the changes are mostly in gcc/Makefile.in or some gcc/*.mk
I believe.

Tell us if that helps!

Cheers.
