current trunk (including all changes from 20091223), native build configured
with --with-arch=armv7-a --with-float=softfp --with-fpu=vfpv3-d16
--with-mode=thumb, fails in stage3 (--with-mode=thumb the option to trigger
this):

if [ x"-fPIC" != x ]; then \

#define BLOCKSIZE 4096
#if BLOCKSIZE % 64 != 0
# error "invalid BLOCKSIZE"
#endif

building with -O0 doesn't show the error, just adding -save-temps as well :-/

going on with the build, more warnings:

../../src/gcc/hwint.h:59:5: warning: integer overflow in preprocessor
expression

#if HOST_BITS_PER_LONG >= 64 || !defined NEED_64BIT_HOST_WIDE_INT

../../src/gcc/../libcpp/include/cpplib.h:251:27: warning: integer overflow in
preprocessor expression

#if CHAR_BIT * SIZEOF_INT >= 32
