Thanks for the quick answer Jonathan.
I've tried to remove the inline from the definition in the source file 
, add even add an explicit declaration like:

circle.c:

     #include <math.h>
     #define PI 3.141592
     float area(float radius);

     float area(float radius)
     {
         return pow(PI*radius, 2);
     }

Still, when I try to link with the library I get the same warning and 
the code isn't inlined. Could you show an example for the proper syntax?
