Kernel compile problem

Question

in arch 0.7, when i compile redhat hat kernel 2.4.21-27.0.1.EL, gcc 3.4.3 complains:
gcc -D__KERNEL__ -I/data/linux-2.4.21-27.0.1.EL/include -Wall -Wstrict-prototypes -Wno-trigraphs -O3 -fno-strict-aliasing -fno-common  -Wno-unused -funroll-loops -fomit-frame-pointer -fomit-frame-pointer -pipe -freorder-blocks -mpreferred-stack-boundary=2 -march=pentium4   -DKBUILD_BASENAME=main -c -o init/main.o init/main.c

but when i compile the kernel src in redhat as 3 with the same kernel config , compiling options and kernel compiling procedure, everything is ok. the gcc info:

gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-20)
what's the problem ? it's something between gcc 3.4 and kernel 2.4.21 (or redhat ?) ? how to resolve this problem ?

hmmm if you need the patch Con Kolivas has a patch... idk if this is the exact need.
1g lowmem?
Many machines now have exactly 1Gb ram and the standard memory split on i386 does not allow you to use more than 896Mb ram without enabling high memory for at least 4Gb. The problem is that this incurs an overhead whereas we can simply change this split with this patch to allow i386 architectures to use up to 1Gb ram without enabling highmem. This is configurable if HIGHMEM is disabled.
I also don't know if his old patches have the patch or if the current will work on the 2.4 kernel..
Just looked around and found the 2.4 are now Ick patchset and i don't see that... CK does have a server patch... If anything just get the 2.6 CK server patchset...   2.6 is stable, but how am I to say I've only used 2.6... Go with 2.6 ck server.
websites:  CK patchset 2.6
ICK 2.4 patchset
i really want a huge kernel space, and i can't find the 4G kernel space vm patch for 2.4 at these links
thanks anyway
