I've got strange error when run ocamlbuild[.byte or .native] compiled
using MINGW.

"c:/prog/mingw/msys/1.0/bin/sh.exe"-2.04$ ocamlbuild
'tput' is not recognized as an internal or external command,
operable program or batch file.
Fatal error: exception Unix.Unix_error(3, "close_process_in", "")

Also I get the same error when trying compile ocaml using ./build/fastworld.sh
somewhere near the folowing lines:
...
+ cp _build/myocamlbuild boot/myocamlbuild.native
+ ./boot/myocamlbuild.native ocamlc.opt.exe ocaml.exe
otherlibs/win32unix/unixsupport.h otherlibs/win32unix/cst2constr.h

 camlp4/Camlp4Filters/Camlp4TrashRemover.o
'tput' is not recognized as an internal or external command,
operable program or batch file.

Is anyone had working ocamlbuild on mingw system?
