Bug#640432: libqhull: Qhull requires __POWERPC__ to be defined to a value

[mycae]

Package: libqhull5
Version: 2009.1-1
Severity: normal
File: libqhull

I have been packaging a program that uses wx and qhull simultaneously. My package built under all (nonBSD) arches except powerpc.
https://buildd.debian.org/status/fetch.php?pkg=3depict&arch=powerpc&ver=0.0.7-1&stamp=1313966886

The problem occurs when you include qhull after including wx:
/usr/include/qhull/qhull.h:36:30: error: operator '&&' has no right operand

After a little digging around, I found the following hack works around the problem:

 //QHull library
+//Build fix for qhull ; wx defines powerpc without
+//assigning a value, causing build fail on powerpc
+#ifdef __POWERPC__
+	#pragma push_macro("__POWERPC__")
+	#define __POWERPC__ 1
+#endif
 extern "C"
 {
 	#include <qhull/qhull_a.h>
 }
+#ifdef __POWERPC__
+	#pragma pop_macro("__POWERPC__")
+#endif

The problem comes when you get to line 36 of 
/usr/include/qhull/qhull.h :

#if __MWERKS__ && __POWERPC__

which I think should be:

#if defined(__MWEKS__) && defined(__POWERPC__)

I don't think wx is faultless here, but can this be patched?
