--- Comment #4 from Michael Deutschmann <michael at talosis dot ca> --- > According to [1], 4.7.1 is already OK, so > 4007 should be enough. But 4.7.0 isn't OK, so >= 4007 isn't enough. (> 4007 is functionally equivalent to >= 4008.) Note that this does make fixing 4.7.4 (which I suggest should be done otherwise a person starting with 4.7.0, no C++, and a cmov-less processor will face a circuitous route up to the current version.) a little more complicated. GCC_VERSION >= 4007 isn't good enough, but GCC_VERSION >= 4008 would mean that 4.7.4 would never include the MMX code when compiled with itself. Some would call that a regression. It's a simple matter of preprocessor programming to check the patchlevel too, but it will be an ugly #if statement.... If only there was a NOT_STAGE_1 macro... (is there?).
