ZSH 4.3.6 fails to compile (module.c: 1453) on AIX 5300-08-01 (AIX 5.3 TL 8), ZSH 4.2.7 compiles

Hi. I'm trying to build zsh 4.3.6 on AIX 5300-08-01 using gcc 4.2.4
and Autoconf 2.61. Configure works fine, but the build fails after
some time with:

This should fix that bit... unfortunately I am writing this completely
blind for AIX, so please report any further problems.

Thanks Peter, that did the trick for module.c, it compiles. Though
make fails a bit after that.

Here's the ./configure output, this one works quite well:

I'm using gmake 3.81 btw:

"struct winsize" is used throught the zsh source; this suggests that it's
not being defined in this case because of different code options.  The
obvious candidate is _XOPEN_SOURCE_EXTENDED, which has caused problems on
other systems.

The best I can think of is therefore to turn that off, which requires
rebuilding configure.  Not defining _XOPEN_SOURCE_EXTENDED might have side
effects in curses.

If it's not easy to track down what's going on, it might simply want to set
the "link=no" against the zsh/curses line in config.modules and run "make
prep" before compiling so as not to compile zsh/curses.  It's not currently
required by anything else.
