You could also modify the startupcode to call the contructors in
the right order. Check the cyg_hal_invoke_constructors function in
hal/mips/arch/v1_1/src/hal_misc.c in eCos 1.1. I did like that to
make eCos 1.1 compile with some old gcc-arm-coff targeting StrongARM.
However, IMO, that was is not a very neat solution.
