[libXau] cannot compile libXau-0.1.1 on aix: wrong compiler option '-include'

Hi everybody,

When attempting to build libXau-0.1.1 on aix 4.3.1 with IBM/ANSI-C
compiler VAC 5.0.7,
I got this error

make  all-am
make[1]: Entering directory `/local/temp/src/libXau-0.1.1'
source=3D'AuDispose.c' object=3D'AuDispose.lo' libtool=3Dyes \

make[1]: *** [AuDispose.lo] Error 1
make[1]: Leaving directory `/local/temp/src/libXau-0.1.1'
make: *** [all] Error 2

-I/local/include -include config.h -I/local/include   -g -c -o
                 ^^^^^^^^^^^^^^^^^^
atually '-include' is not a valid compiler option

FWIW, here's the patches I used to remove it from the Makefile
generation

Hope this helps
