Hi,

I have a very strange problem when I try to make a relocatable dll.

I use the following procedure, all objects are compiled with debug (ie contains
..stab & .stabstr sections):

	ld $(LDFLAGS) --dll -e $(%entry) -o tmp.dll --base-file base $(%obj)
	dlltool --dllname $@ --base-file base --output-exp tmp.exp --def
dll.def
	ld $(LDFLAGS) --dll -e $(%entry) -o $@ tmp.exp $(%obj)


-1) Some relocations appear for sections .stab & .idata($3) ???

-2) After the 2nd link the export section (.edata) is inserted before the
import section (.idata). The vma's are changed but the relocations generated by
the first pass aren't updated => the relocations are applyed in the wrong
sections.

----> Workaround: add another pass ( dlltool ... & link )

	I think the problem comes from the first remark (relocations for .stab
& .idata) but I'm really not an expert, I tried to see with debugger what's
going on but the code of linker remains obscure for me.

Any kind of help will be welcome ...

Best regards.
