getting memory errors when natively bulding native gnu gcc 3.3.2 compiler on PQ2FADS-VR with 32 MB DRAM memory

["Povolotsky, Alexander" <Alexander dot Povolotsky at marconi dot com>]

Hi,

I am trying to natively build native gnu gcc 3.3.2 compiler from the source
tar ball on PQ2FADS-VR (MPC 8275) 
with 32 MB DRAM memory, running "vanilla" Linux 2.6.8-rc4 kernel (built by
me) with NFS mounted root file system ("/fadsroot") and getting memory
errors (see listing below).

For such (as above) native building I use another "native" gnu gcc 3.3.2
compiler,
which, in turn, was generated via cross-compiling on cygwin
(BIG Thanks to Kai Ruottu for his GREAT help on that!)
and placed on NFS mounted root file system.

Note that on cygwin I already had good working/tested gcc crosscompile for
PQ2FADS-VR (MPC 8275) - I used it
to build U-boot, "vanilla" Linux 2.6.8-rc4 kernel 
(built by me with BIG Help from cross-compiling community and Kumar Gala),
lmbench, ctcs (Cerberus Test Control System).

Prior to attempting to natively build native gnu gcc 3.3.2 compiler
from the source tar ball on PQ2FADS-VR (MPC 8275)
- gnu coreutils, gawk and sed were also cross-compiled on cygwin
and placed on NFS mounted root file system).

gcc version 3.3.2

I have tried two variants of doing it ( build native gnu gcc 3.3.2 compiler
from the source tar ball):

a) 
make CFLAGS='-O' LIBCFLAGS='-g -O2'LIBCXXFLAGS='-g -O2
-fno-implicit-templates' bootstrap

b) using script (see below listed), which was modified (by me) from the
script,
 originally provided to me (for cross-compiling on cygwin) by Kai Ruottu
(see above).

In either case, I am getting errors (oom-killer: gfp_mask=0x1d2 ... - see
below)
