Inline functions in C99

[Paulo J. Matos]

Hi all,

I'm using std=c99 for my project and I've had gcc 4.1.2 where
everything compiled well. Now I've moved to 4.2.3 where I get:
cc1: warnings being treated as errors
timemgm.c:37: warning: C99 inline functions are not supported; using GNU89
timemgm.c:37: warning: to disable this warning use -fgnu89-inline or
the gnu_inline function attribute
timemgm.c:43: warning: C99 inline functions are not supported; using GNU89
timemgm.c:52: warning: C99 inline functions are not supported; using GNU89

What was the change between gcc version so that now I can't inline
functions? Why is this? If I can't inline functions, won't this reduce
the efficiency of my binary, or at least hinder my possibilities of
optimizing it?

Cheers,
