But the failure mode is assembling assembler source - GMP should
arrange to not use the compiler driver to assemble but to call
an assembler directly for assembler source. (yes, the compiler
driver knows which assembler to use, so it's certainly convenient
to use it - but I can see people using a compiler with a built-in
assembler that expects Intel assembler operand ordering instead
Just a suggestion ...
