So we just need to define both. Sigh. I wonder who has come up with this ridiculous rename idea in the first place? Now suddenly there is some work to do for us and the others, which serves no real purpose... It might be even better to just reimplement the non-portable htole32 and letoh32 functions. They only need a few lines of code and the speed of the operations done with their help is not critical to us. But I'm not really asking you to do this right now. > --- > fel.c | 4 ++-- > phoenix_info.c | 4 ++-- > pio.c | 4 ++-- > 3 files changed, 6 insertions(+), 6 deletions(-) > > diff --git a/fel.c b/fel.c > index ec9a3ed..78c1465 100644 > --- a/fel.c > +++ b/fel.c > @@ -15,8 +15,8 @@ > * along with this program.
