egcs-1.1.1 cross: i586-lynxos-gas says "Alignment not a power of 2"

Thanks. I found a symbol in gcc/auto-host.h, HAVE_GAS_BALIGN_AND_P2ALIGN 
which the configure had undefined. However, I verified that the AS of my 
LynxOS 2.5 target DOES support those statements. Apparently, the config 
is for an older LynxOS version where these were not yet supported (?)
After defining the HAVE_GAS_BALIGN_AND_P2ALIGN, I am no longer getting 
the "power of 2" error.

I am now a bit farther, but stumbling on libgcc1-test:

./xgcc -B./ -DCROSS_COMPILE -DIN_GCC    -g -I./include     -c ./libgcc1-test.c
./libgcc1-test.c:101: warning: conflicting types for built-in function `memcpy'

Here is the beginning of libgcc1-test.s:

        .file   "libgcc1-test.c"
gcc2_compiled.:
__gnu_compiled_c:
.stabs "/var/kelloggs_extra_space/egcs-1.1.1/gcc/",100,0,0,Ltext0

.Ltext0:
.stabs "int:t1=r1;0020000000000;0017777777777;",128,0,0,0
.stabs "char:t2=r2;0;127;",128,0,0,0

I can assemble this file without error on the actual LynxOS-2.5 target;
this must be a config problem (probably again LynxOS version related) with 
the i586-lynxos-gas cross assembler.

Right, thanks. binutils-2.9.1
