You do not need LP64 model to manage large files. Zsh should already
detect LFS support and configure itself accordingly. See --enable-lfs
flag to configure. This of course assumes that your version of Solaris
does support LFS.

Has been done long long ago.

I once tried to build Zsh in LP64 mode but I guess I had some problems
and I do not think it is really needed. LP64 is needed for programs
requiring very large address space, like database servers. Zsh hopefully
will never requires address space above 1GB and if it does it must be a
bug :-)

Of course patches that allow clean LP64 model for zsh are welcome.
