Oh! Thanks. I was wondering who was the author of DXE, because all
troubles are not overcome yet. This change is to use gcc to pick up
the right directories instead of hardcoded values: 
--- src.org/makefile.inc        Sat May 30 21:33:24 1998
+++ src/makefile.inc    Sun Jul  5 04:49:22 1998

 C = $(LIB)/crt0.o
 L = $(LIB)/libc.a

-LINK = $(CROSS_LD) -s $(LDFLAGS) $(filter %.o,$^) $(filter-out

 OBJS := $(addsuffix .o, $(basename $(SRC)))

But then compilation in src/libemu fails. I had to do this change
(handmade patch):
--- src.org/libemu/makefile
+++ src/libemu/makefile
$(BIN)/emu387.dxe : src/emu387.o src/emudummy.o
-       $(HOSTBIN)/dxegen.exe $(BIN)/emu387.dxe __emu_entry src/emu387.o id_emu.o src/emudummy.o -L../../lib -lgcc -lc -lgcc
+       $(HOSTBIN)/dxegen.exe $(BIN)/emu387.dxe __emu_entry src/emu387.o id_emu.o src/emudummy.o -L../../lib -L../../lib/gcc-lib/djgpp/2.81 -lgcc -lc -lgcc

I. e. hardcode the lib/gcc-lib/djgpp/2.81 directory to make the linker
find the library libgcc.a. This is because dxegen uses ld. So I think
somebody has to in and change dxegen.

Hmm, while writing this the idea (hit me) that perhaps it's possible to use
DXE_LD="gcc -Wl,a,lot,of,options" when compiling dxegen?

Well, DJ? What happens?
