Thanks for your help!
That wasn't so difficult, once I've refreshed my memory.
Here is a new patch, using the export.txt whenever it does exist.
I have tested it with v13.4 : it's OK.
Patch for 14beta3 should be the same since there was no change for src/Makefile.shlib between v13 and v14.

Here's an example from elsewhere in Makefile.shlib:
# If SHLIB_EXPORTS is set, the rules below will build a .def file from that.
# Else we just use --export-all-symbols.
ifeq (,$(SHLIB_EXPORTS))
$(shlib): $(OBJS) | $(SHLIB_PREREQS)
$(CC) $(CFLAGS) -shared -static-libgcc -o $@ $(OBJS) $(LDFLAGS) $(LDFLAGS_SL) $(SHLIB_LINK) $(LIBS) -Wl,--export-all-symbols -Wl,--out-implib=$(stlib)
else
DLL_DEFFILE = lib$(NAME)dll.def
$(shlib): $(OBJS) $(DLL_DEFFILE) | $(SHLIB_PREREQS)
$(CC) $(CFLAGS) -shared -static-libgcc -o $@ $(OBJS) $(DLL_DEFFILE) $(LDFLAGS) $(LDFLAGS_SL) $(SHLIB_LINK) $(LIBS) -Wl,--out-implib=$(stlib)
UC_NAME = $(shell echo $(NAME) | tr 'abcdefghijklmnopqrstuvwxyz' 'ABCDEFGHIJKLMNOPQRSTUVWXYZ')
$(DLL_DEFFILE): $(SHLIB_EXPORTS)
echo 'LIBRARY LIB$(UC_NAME).dll' >$@
echo 'EXPORTS' >>$@
sed -e '/^#/d' -e 's/^\(.*[ ]\)\([0-9][0-9]*\)/ \1@ \2/' $< >>$@
