For example (Richard's address was a giveaway :-) http://lxr.linux.no/source/arch/m68k/fpsp040/do_func.S#L33 It looks like that code is wasting its time running cpp when only one file actually uses #include, though. Speaking of good interface design, I have to say I admire gas's comment syntax: Anything from the "line comment" character to the next newline is considered a comment and is ignored. The line comment character is `;' for the AMD 29K family; `;' on the ARC; `@' on the ARM; `;' for the H8/300 family; `!' for the H8/500 family; `;' for the HPPA; `#' on the i386 and x86-64; `#' on the i960; `;' for the PDP-11; `;' for picoJava; `;' for Motorola PowerPC; `!' for the Hitachi SH; `!' on the SPARC; `#' on the ip2k; `#' on the m32r; `|' on the 680x0; `#' on the 68HC11 and 68HC12; `;' on the M880x0; `#' on the Vax; `!' for the Z8000; `#' on the V850; see *Note Machine Dependencies::.

I think the best reasonableness/correctness tradeoff is probably to just not distribute input files called .s or .S. They probably occur infrequently compared to C or C++, and also assembly is probably sufficiently cheaper than compilation that it will not hurt performance too much. > It might, indeed.
