[Qt-interest] Qt 4.5 on Mac OSX: Attempt to build quad frameworks omits -arch i386 from CFLAGS/CXXFLAGS

[Rush Manbert]

Based on information from Mike Jackson, I attempted to build a shared,  
framework-based, quad library version of Qt 4.5.

My configure command as:
time ./configure -prefix /Users/rmanbert/temp/qt4.5.0-quadDylib -debug- 
and-release -no-qt3support -cocoa -framework -webkit -arch i386 -arch  
x86_64 -arch ppc -arch ppc64 -platform macx-g++

After building qmake, configure shows me this:
Build type:    macx-g++
Architecture:  macosx ( i386 x86_64 ppc ppc64 )
Using framework: Cocoa

which looks fine, although the architecture specs repeat. It then goes  
on to create all of the Makefiles.

I ran make and noticed that none of the compile commands included - 
arch i386. They has the other 3 architectures specified, but not i386.

I stopped the make, found some object files and ran lipo -info on  
them. Lipo says "Architectures in the fat file: qmutex.o are: ppc64  
ppc7400 x86_64"

Since I specified the i386 architecture first in my configure command  
and it was missing in the Makefiles, I tried again with ppc specified  
first. The Makefiles once again define these flags:
CFLAGS        = -pipe -g -gdwarf-2 -arch ppc64 -Xarch_ppc64 -mmacosx- 
version-min=10.5 -arch x86_64 -Xarch_x86_64 -mmacosx-version-min=10.5 - 
arch ppc -Wall -W $(DEFINES)
CXXFLAGS      = -pipe -g -gdwarf-2 -arch ppc64 -Xarch_ppc64 -mmacosx- 
version-min=10.5 -arch x86_64 -Xarch_x86_64 -mmacosx-version-min=10.5 - 
arch ppc -Wall -W $(DEFINES)
LFLAGS        = -headerpad_max_install_names -arch ppc64 -Xarch_ppc64 - 
mmacosx-version-min=10.5 -arch x86_64 -Xarch_x86_64 -mmacosx-version- 
min=10.5 -arch ppc

and again the i386 is missing.

I'm building on an Intel Mac, so it almost seems like the Makefiles  
assume there will be a implicit compilation for i386, but the lipo  
results say that's not true.

I suspect this is a bug, but maybe I have done something wrong. Does  
anyone else have experience with this?
