[ECOS] error with __cxa_atexit and __dso_handle

["Santiago Lafon - Controles S.A." <slafon at controles dot com>]

I want to upgrade my arm-alf toolchan to the latest GNU tools

Some time ago, i made a toolchain with:
    binutils 2.14
    gcc-core 3.3.1
    gcc-g++  3.3.1
    newlib   1.11.0
    insight  5.3

Now i made a new one with
    binutils 2.18
    gcc    4.2.1
    newlib    1.15.0
    insight    6.6

I can build ecos without apparent problems (i'm working with a simple 
eb40a target).

Then, when i try to make a simple application (or if i try to make ecos 
tests), it's when my problems appears.

I get lots of errors like this:

work/eCos/lib/eb40a/rom/eb40a_rom_sin_net_v00.20_install/lib/extras.o: 
In function `__static_initialization_and_destruction_0':
/opt/ecos-snap-2007-09-09/packages/io/fileio/current/src/misc.cxx:105: 
undefined reference to `__cxa_atexit'

/opt/ecos-snap-2007-09-09/packages/io/fileio/current/src/misc.cxx:125: 
undefined reference to `__cxa_atexit'
/opt/ecos-snap-2007-09-09/packages/io/fileio/current/src/misc.cxx:532: 
undefined reference to `__dso_handle'

Could someone help me?

Thanks
