+Starting with GCC 4.3.0, the compiler supports the <c>-march=native</c> switch |
| 51 |
+which turns on CPU autodetection and optimizations that are worth being enabled |
| 52 |
+on the processor the GCC is running at. This is a problem with <c>distcc</c> as |
| 53 |
+it allows mixing of code optimized for different processors (like AMD Athlon and |
| 54 |
+Intel Pentium). <e>Don't</e> use <c>-march=native</c> or <c>-mtune=native</c> in |
| 55 |
+your <c>CFLAGS</c> or <c>CXXFLAGS</c> when compiling with <c>distcc</c>. |
