Error in _fixunsdfsi for m68040

[Mario Giovinazzo]

I can't build a 68k C cross compiler under cygwin starting from:

 

        binutils-2.16
        newlib-1.13.0
        gcc-4.0.0

 

because an error compiling libgcc2.c in function _fixunsdfsi for M68040

Using binutils-2.15 there is no more error and the generated 68k cross compiler works properly.

 

this is the message in log file:
