Interesting. The compiler doesn't do x86_64 by default --- you have to
enable it in the compile.
Any idea how to handle this in our builds? It doesn't seem like a
property of the OS as much as a property of the compiler --- we
already do 64-bit on some platforms without flags.
What is the full ac_cv_host value in config.log?
ac_cv_host=i386-pc-bsdi4.3.1
I assume there is something special in the first field before the dash
that could trigger these compile/link flags automatically.
As I already mentioned, the s_lock.h changes will appear in 7.4 and are
in CVS now.
