Problem of C program include "math.h"

[willisfield]

Hi, aleix!
    You are right, I made a mistake in compiling the
*.c files, the -lm option should be added in the last
place of the compile command, but I added it before
the *.c files. By the way, the return of the 
"sparc-rtems-gcc -v " command is: gcc version 3.2.3.
    Thank you very much!
