Building mips cross compiler on mingw

[Dave Murphy]

Hi,

I've been having some trouble building gcc 4.0.1 for mips target on a 
mingw host

The build fails at this point

saving temp files and adding -v gives this

I've attached the saved temp files.

The same build process works fine on linux and I've compared output. The 
preprocessed source is identical barring paths. The assembly output 
differs only in the function prologue

on mingw built compiler

__muldi3:
    .frame    $sp,0,(null)        # vars= 7640055, regs= 0/0, args= 0, gp= 0

on linux built compiler

__muldi3:
    .frame    $sp,0,$31        # vars= 0, regs= 0/0, args= 0, gp= 0

can anyone point me in the right direction? I'm not quite sure what I 
should be looking for.

Dave
