FYI: I think the problem is related to a rule (which contained a failing mv
command because of Cygwin's .exe mangling) in stdlib/Makefile.nt; if I amend
the following rule, everything seems to work:

camlheader camlheader_ur: headernt.c ../config/Makefile
	# $(BYTECC) $(BYTECCCOMPOPTS) $(BYTECCLINKOPTS) -o camlheader.exe
headernt.c
	# mv camlheader.exe camlheader.
	$(BYTECC) $(BYTECCCOMPOPTS) $(BYTECCLINKOPTS)
-DRUNTIME_NAME='"$(BINDIR)/ocamlrun"' headernt.c -o tmpheader$(EXE)
	strip tmpheader$(EXE)
	mv tmpheader$(EXE) camlheader
	cp camlheader camlheader_ur

These changes are in line with the camlheader, camlheader_ur rules in
Makefile.

I think this is a recent Mingw problem? I just tried building Ocaml 3.08.1
with the same version of Mingw and the same problem occurs, where it was
working in the past with an older Mingw setup.

I think the binaries are corrupt. Here's the output of dumpbin on ocamlc.exe
and ocamlc.opt.exe (note that ocamlc.exe doesn't work, and ocamlc.opt.exe
does work):

Perhaps you have *too much* memory.

Your situation reminds me of problem I've had with > 2GB disks and older
installation programs who computed remaining disk space with 32 bit integers
and thus failed. OCaml maybe computes remaining memory with 31 bits so 1 GB
is the max (on 32 bit machines) ?
