I have not looked at your code. However, I can tell you that on
32-bit x86 floating point function arguments are normally passed on
the stack and on 64-bit x86 floating point arguments are normally
passed in the xmm registers. There are various ways that you can
change this default behaviour, but if you are seeing an unexpected
change then I would guess that you changed from 32-bit compilation to
64-bit compilation.

Probably I have. But when I pass the -m32 parameter I get an unexpected
error:
/usr/include/gnu/stubs.h:7:27: fatal error: gnu/stubs-32.h: No such file
or directory
which also prevents me from compiling the compiler under Fedora 17. This
means that I am both not able to compile programs in 32-bit mode and
help you with the compiler.
Is there a solution and what are the exact alternatives you refer to?
