compiling glib-2.6.4 as 32bit on AMD64

[Bernd Knorr <bernd knorze de>]

Hi,

I'm just building 64bit-LinuxFromScratch for Athlon64. To be able to run 32bit 
apps like Firefox I want to provide also a 32bit version of the needed libs 
(like GTK+ and all its dependencies). When compiling glib-2.6.4 I pass the 
-m32 flag to the compiler in order to build a 32bit version. No other changes 
in the build procedure. The build fails in an early stage with the following 
error:
gcc -DHAVE_CONFIG_H -I. -I. -I.. -I.. -DG_LOG_DOMAIN=\"GLib\" 
-DG_DISABLE_CAST_CHECKS -DG_DISABLE_DEPRECATED -DGLIB_COMPILATION -pthread 
-m32 -Wall -MT gatomic.lo -MD -MP -MF .deps/gatomic.Tpo -c gatomic.c  -fPIC 
-DPIC -o .libs/gatomic.o
/tmp/ccUH2LHC.s: Assembler messages:
/tmp/ccUH2LHC.s:75: Error: suffix or operands invalid for `cmpxchg'
make[4]: *** [gatomic.lo] Fehler 1

If I pass "--build=i686" to the configure-script, glib builds fine, but 
results only in static libs, which is not what I want.

Any suggestions ?
