Subject: gcc command line ordering question

I have a tiny little snippit of code here (test.c):

char ldap_init();
int main(int argc, char **argv)
{
  ldap_init();
  return 0;
}

I expect (want) a runtime error but I do expect it to compile when
linked with the openldap libraries. Here's my quandery:

vv# gcc -L/usr/local/lib -I/usr/local/include -lldap -llber test.c
/tmp/ccj67244.o: In function `main':
/tmp/ccj67244.o(.text+0x7): undefined reference to `ldap_init'

Very odd... but if I changed the ordering of the arguments:

vv# gcc -L/usr/local/lib -I/usr/local/include test.c -lldap -llber
vv#

It compiles fine. I thought gcc proccessed files in the order in which
they appeard? I further thought that the only difference between
specifying a fullname and using -l was that -l surrounding the name
with lib*.a and searched multiple directories. If thats all true why
would the ordering matter here?
