How to disable compiler's options "-MT DOE.o -MD -MP -MF .deps/DOE.Tpo" automately generated by autoconf & automake

When I invoke a make command, the command reads (on the screen):

ccppc -I. -I../../h -Wall -fno-builtin -fno-for-scope -mstrict-align -mcpu=604 -DCPU=PPC604 -mlongcall -MT DOE.o -MD -MP -MF .deps/DOE.Tpo -c -o DOE.o DOE.c

I understand where -I. -I../../h -Wall -fno-builtin -fno-for-scope -mstrict-align -mcpu=604 -DCPU=PPC604 -mlongcall comes from, because I defined them.

AM_CFLAGS=-Wall -fno-builtin -fno-for-scope -mstrict-align -mcpu=604 -DCPU=PPC604 -mlongcall AM_CPPFLAGS = -I../../h

However, I don't know where -MT DOE.o -MD -MP -MF .deps/DOE. comes from. I want to disable it.

I digged into the Makefile,and find the line related to -MT DOE.o -MD -MP -MF .deps/DOE..

.c.o:
    $(COMPILE) -MT $@ -MD -MP -MF $(DEPDIR)/$*.Tpo -c -o $@ $<
    $(am__mv) $(DEPDIR)/$*.Tpo $(DEPDIR)/$*.Po

I just want to remove -MT $@ -MD -MP -MF $(DEPDIR)/$*.Tpo, for I get errors because of it.

the -M flags are added by autoconf to enable dependency tracking. you can disable them, by specifying by running:

 ./configure --disable-dependency-tracking

in general autoconf should figure this out by itself. did you specify the compiler (ccppc seems fairly non-standard to me) when running configure or did you only change to it when running make?
