Summary: configure.in Assumes cc_r Exists on AIX.

Initial Comment:
Running plain `./configure' on an AIX 3.2.5 machine 
fails.

    configure:966: checking whether the C compiler 
        (cc_r  ) works
    configure:982: cc_r -o conftest    conftest.c  
        1>&5
    ./configure: cc_r: not found
    configure: failed program was:
    
    #line 977 "configure"
    #include "confdefs.h"

    main(){return(0);}

Here's details about the machine.
    
    $ uname -a 
    AIX anon 2 3 000038834100
    $ oslevel
    >3250

cc_r doesn't exist.  cc does.  Running configure thus

    $ ./configure --without-gcc

as a workaround lets configure successfully complete.

configure.in assumes $CC should be cc_r if no
--with-gcc or --without-gcc option is given and if the 
system is AIX.  This seems wrong.  Instead, perhaps it 
should search for the first cc that works with an
order of preference to cc_r, then cc.

PS.  No, it doesn't continue to build sucessfully.  But
that's another bug report I've yet to raise and is
unrelated AFAICS to this problem.

I've attached a possible patch.  It seems right in theory
but I'm not experienced with autoconf.  Unfortunately, I
can't test the patch because I can't re-generate configure
on this system -- I guess I have incompatible versions of
autoconf, automake, etc.  If you want to email me the
resulting configure I'd be happy to try it.

Thanks for the report.  Can you come up with a patch?  I can
probably bodge something together if not, but it's obviously
easier to test.

Does the build actually work after
./configure --without-gcc
?
