I tried this but, unfortunately, the "configure" command fails.
Here's what appears to be the relevant info from config.log:
=======================
configure: failed program was:
| /* confdefs.h.  */
| #define _GNU_SOURCE 1
| #define _NETBSD_SOURCE 1
| #define __BSD_VISIBLE 1
| #define _BSD_SOURCE 1
| #define _BSD_TYPES 1
| /* end confdefs.h.  */
|
| int
| main ()
| {
|
|   ;
|   return 0;
| }
configure:2647: error: C compiler cannot create executables
See `config.log' for more details.
============================
This is on a Macbook with Leopard installed.

I tried compiling a simple c program (hello world), something that I
have not done in *years* and it failed.  It appears as though gcc has
a problem  :-(

I can create an object file  (via gcc -c hello.c) but not an
executable...

====
andre-roberges-computer:Downloads andre$ gcc -o hello hello.c
/usr/bin/ld: /usr/lib/gcc/i686-apple-darwin8/4.0.1/../../../
libSystem.dylib unknown flags (type) of section 6
(__TEXT,__dof_plockstat) in load command 0
collect2: ld returned 1 exit status

Any help would be appreciated!
