uld simplify things slightly.
You should also most likely use concat here instead of
XNEWVEC/strcpy/strcat which will also simplify the code.
Like string = concat (DEFAULT_REAL_TARGET_MACHINE, "-", commands[0].prog);
I think this should be done for more than just as/ld but also objcopy

C with? I suspect this is making a difference. It might also
be the sparc compiler that both of you two are using is causing wrong
code with some more complex C++ code even though it is at -O0.
The adding of the deconstructor to Value_Range might be causing the
structure to become a "non-POD" and different argument passing and it
was broken even at -O0 (this is just a guess).
