gtk+-2 compile error on amd64: gmem.c failed to allocate XXX bytes

Hi, I have a problem compiling gtk+-2 on my athlon64 linux machine (Cross-LFS-system with gcc-4.0.2, glibc-20051024, glib-2.8.3, gtk+-2.8.6) I get the following error: make[4]: Entering directory `/home/knorze/Software/BLFS/X_and_Window_Managers/X_Libraries/gtk+-2.8.6/gtk/stock-icons' GDK_PIXBUF

compiling glib-2.6.4 as 32bit on AMD64

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.
