Most of guts for c++filt is in cplus-dem.c, which is included with
GNU liberty.  If you look at the Makefiles and the source...

cplus-dem.o: $(BASEDIR)/libiberty/cplus-dem.c $(INCDIR)/getopt.h
	$(CC) -c -DMAIN $(INCLUDES) $(HDEFINES) $(TDEFINES) $(CFLAGS) $(BASEDIR)/libiberty/cplus-dem.c

$(DEMANGLER_PROG): cplus-dem.o $(LIBIBERTY) underscore.o version.o
	$(CC) $(CFLAGS) $(LDFLAGS)  -o $(DEMANGLER_PROG) cplus-dem.o $(LIBIBERTY) $(EXTRALIBS) underscore.o version.o

The "-DMAIN" turns on the compilation of main() in cplus-dem.c.
underscore.o adds "int prepends_underscore = <whatever is
appropriate>", and version.o is self-explanatory.

Instead of dragging in the large binutils package and throwing 99.9%
away, it may be better to rewrite the liberty Makefile to generate
c++filt, or write an equivalent main() driver and link with with -liberty.

Actually, it is

  ivPainter::RasterRect(ivCanvas *, int, int, ivRaster *)

And, yes, the "iv" prefixes are very important, at least for picky
utilities like ld. :^)
