-------------------------------------

In libzend the '-Ae' option is missing, thus no Ansi 
support and the compilation fails.

Also, while it doesn't really cause any problems, for
the rest of the compilation, -Ae is given twice to cc.

-D_HPUX_SOURCE is also defined automatically when you 
use -Ae, so it can be removed as well as long as -Ae
is used.
