Brilliant , Thanks
What an error !!
I think we should report this pathscale , or see if they have bug report
allready
I suspect that the cc "compiles" prog.c to prog.s and therefore overwrites our
prog.s , and when we link them we get two mains , and an undefined reference
to cpuid
I put change in trunk and mpir-1.1 branch.
Thanks
