[Dev-C++] Why this bug? Error in the compilation of the Makefile.win

[<jul...@er...>]

The Makefile.win contains:
=20
--- BEGIN Makefile.win BEGIN ---
# Project: nada
# Makefile created by Dev-C++ 4.9.8.0
=20
CPP  =3D g++.exe
CC   =3D gcc.exe
WINDRES =3D windres.exe
RES  =3D=20
OBJ  =3D NadaMain.o $(RES)
LINKOBJ  =3D NadaMain.o $(RES)
LIBS =3D  -L"C:/mingw/lib"=20
INCS =3D  -I"C:/mingw/include"=20
CXXINCS =3D  -I"C:/mingw/include/c++"  -I"C:/mingw/include/c++/backward"
-I"C:/mingw/include"=20
BIN  =3D nada.exe
CXXFLAGS =3D $(CXXINCS)=20
CFLAGS =3D $(INCS)=20
=20
.PHONY: all all-before all-after clean clean-custom
=20
all: all-before nada.exe all-after
=20
=20
clean: clean-custom
                        rm -f $(OBJ) $(BIN)
=20
$(BIN): $(LINKOBJ)
                        $(CC) $(LINKOBJ) -o "nada.exe" $(LIBS)
=20
NadaMain.o: NadaMain.c C:/mingw/include/stdlib.h
C:/mingw/include/_mingw.h C:/mingw/include/stddef.h =20
                        $(CC) -c NadaMain.c -o NadaMain.o $(CFLAGS)
--- END Makefile.win END ---
The compiling of the project don't successful with error "multiple =
targets
in line (NadaMain.o: NadaMain.c ....)".
In the other hand, if I change the Makefile.win and write:=20
--- BEGIN Makefile.win Changed BEGIN ---
# Project: nada
# Makefile created by Dev-C++ 4.9.8.0
=20
CPP  =3D g++.exe
CC   =3D gcc.exe
WINDRES =3D windres.exe
RES  =3D=20
OBJ  =3D NadaMain.o $(RES)
LINKOBJ  =3D NadaMain.o $(RES)
LIBS =3D  -L"C:/mingw/lib"=20
INCS =3D  -I"C:/mingw/include"=20
CXXINCS =3D  -I"C:/mingw/include/c++"  -I"C:/mingw/include/c++/backward"
-I"C:/mingw/include"=20
BIN  =3D nada.exe
CXXFLAGS =3D $(CXXINCS)=20
CFLAGS =3D $(INCS)=20
=20
.PHONY: all all-before all-after clean clean-custom
=20
all: all-before nada.exe all-after
=20
=20
clean: clean-custom
                        rm -f $(OBJ) $(BIN)
=20
$(BIN): $(LINKOBJ)
                        $(CC) $(LINKOBJ) -o "nada.exe" $(LIBS)
=20
NadaMain.o: NadaMain.c =20
                        $(CC) -c NadaMain.c -o NadaMain.o $(CFLAGS)
--- END Makefile.win Changed END ---
and write "mingw32-make -fMakefile.win" all functions correctly.
Is this problem due to a error configuration?.
