Historically, the concern was that if person A builds the compiler and hands it to person B, person B may have a different assembler or linker than person A. So we force person A to explicitly indicate whether they are using the GNU assembler. However, this general rule is not followed very much. E.g., when using the GNU tools, the configure scripts check for various features of them, which could fail if person B has a different version of the GNU tools installed. So I think it would be reasonable to have the configure script set the defualt for -with-gnu-ld/as based on the tools found at configure time. Ian
