skipping header file depency

hello,
Perhaps somebody could help with the following.
I'm trying to convert some makefiles into aap recipes for microcontroller 
applications which should be compiled with a windows commandline compiler 
with the linux wine emulator.
Because this compiler cannot generate dependencies I run both the linux 
compiler and the uC compiler on the files. 
One header files gives problems because of several preprocessor directives and 
I would like to skip the dep. checking on this file. How to do this?
I've 2 recipes. One is a generic directory with c files and the application 
directory contains a symbolic link to this directory (gen). This directory 
contains the header file which I would like to skip.
Other comments are also welcome. It's my first start, so perhaps many things 
can be improved.

This generic recipe is as follows:

UCCFLAGS = -O\( -OB -V -OZ -OE -OH -E -Isoftools/include -W760 -W782 -W757 
-Igen
BDIR = generic

:action depend c
        :sys $CC -MM $source > $target
        :sys  wine -- softools/SC2000.exe $?UCCFLAGS $source


genfiles =
        adc.c
        alert.c
        board_id.c
        bootp.c
.....
        ISRHandler_c.c

ucosfiles =
        os_core.c
.......
        os_time.c


:attr ucos_ii.h {autodepend = off}
# This doesn't work!!!!!!



_top.Gen_obj = $ucosfiles $genfiles
all : $_top.Gen_obj


The other recipe contains several steps: it generates a file items.c from a 
xml file. And every c files is compiled twice: one time for depencies and a 
crosscompilation. Linking is again separate.
