Re: Kannel & Autoconf

Hi.

1) You must check compiler before libs. Compiler check figures out  
how to call the
compiler, and about all tests call the c compiler. So just transfer  
the bsd library check

2) Most of these things are were fixed when 1) was fixed. However, in  
Darwin, net/if.h
includes sys/socket.h and so sys/socket.h must be tested separately.

Here is the diff:

Note that this is *not* tested with bsds. I hope that someone having  
access can test.
But note that add all new library checks to the relevant configure.in  
section.
