I'm not sure but I think this was done intentionally. The code is:
#if __GNUC__ - 0 > 2 || (__GNUC__ - 0 == 2 && __GNUC_MINOR__ > 5)
With __GNUC__ undefined this will expand to
#if 0 - 0 > 2 || (0 - 0 == 2 && 0 > 5)
(At least this is what the gnu cpp manual says, I hope this is true for
I don't know why the code uses __GNUC__ - 0, maybe this is when __GNUC__ is
defined but empty?
But you are right that
# if __GNUC__ ...
is easier to understand and maybe more portable (I haven't heard of problems
on any platform about this line, however). So I think you can change this.
