So is this style acceptable? (see example below)

// common.h:
int i;
void print();
void inc();

This is not good style. It defines (rather than merely declares) the
variable i in each file that includes common.h. Though, as the
standard and FAQ state, this works on many systems, it is better to
say what you mean, and merely declare i in the header file with
"extern int i", and define it in one of the .c files with "int i".

thanks
i like minimalistic code, but it seems it's not quite ok to leave out
extern here
