latest Xcode for mac 10.5 breaks building of IPP

[heather]

building the ipp (svn 25223) with the latest version of Xcode (version 3.1.3 )

causes this error:

In file included from /usr/X11/include/X11/Xlib.h:64,

from /Users/hswan/bin/default.darwin_x86/include/kapa.h:10,
from pmKapaPlots.h:23,
from pmKapaPlots.c:20:

/usr/X11/include/X11/Xosdefs.h:145:1: error: "_DARWIN_C_SOURCE" redefined
<command line>:1:1: error: this is the location of the previous definition
make[3]: * [libpsmodulesextras_la-pmKapaPlots.lo] Error 1
make[2]: * [all-recursive] Error 1
make[1]: * [all] Error 2
make: * [all-recursive] Error 1

_DARWIN_C_SOURCE is now defined in /usr/X11/include/X11/Xosdefs.h, previously it was not.

[eugene]

how was _DARWIN_C_SOURCE being placed on the command line?

do we have a solution that works for both the old and new versions of Xcode?

this was just a test to see if I could attach a picture.
