(just if you try that on large projects, the compiler's memory usage will go through the roof)
also generating a .a static library in between is unnecessary, you could pass gcc the object files directly (and order is, again, irrelevant)

in case of nonbelievers:

Code:

$ cat >foo.c
int foo(void){return 34;}
$ cat >main.c
int main(void){return foo();} 
$ gcc -o test foo.c main.c && { ./test ; echo $?; }
34
$ gcc -o test main.c foo.c && { ./test ; echo $?; }
34
