49 | ## Note, we have patch this macro compared to official macro as we've |
---|
50 | ## moved down GCC in the list. This was motivated by the fact that |
---|
51 | ## many compilers defined __GNUC__ and therefore the test for GCC have |
---|
52 | ## many false positives and it is better to have that test as late as |
---|
53 | ## possible. |
