The question I have is what causes the build when I don't use the specific rule
and the general rule
"
new-$(DLL_NAME): $(DLL_OFILES) $(DEF_FILE) $(DLL_IMPORTS) $(LIBC) $(LIBM)
Makefi
le winver_stamp
        $(CXX) $(CXXFLAGS) -nostdlib -Wl,-shared -o $@ -e $(DLL_ENTRY)
$(DEF_FIL
E) $(DLL_OFILES) version.o \
        winver.o $(DLL_IMPORTS) $(MALLOC_OBJ) $(LIBM) $(LIBC) -lgcc -lstdc++

dll_ofiles: $(DLL_OFILES)
"
is used?

Now, why do I want to do this in the first place?  I wanted to use -O3 which
adds -finline-functions and autoload.cc and exceptions.cc cause undefined
symbols when building the dll with this switch.  So I want to be specific for
these objects so that I can add the -fno-inline-functions to the formula.

Cheers,
