Zsh on Cray T90

["Richard D. Slater" <rdslater@splash.Princeton.EDU>]

I have gotten zsh-3.0.0 running on our Cray T90 (IEEE processors).  I
needed to make three changes: add code to config.guess to recognize the
machine, add code to config.sub to recognize the machine, and
initialize the variable "val" to 0 in routine getquery in Src/utils.c.
Without doing the latter the routine would always immediately return
with a value 'n' (not a fatal flaw, but annoying).  I've also modified
config.(guess|sub) to recognize the C90 (I think).  I had built
zsh-2.5.03 on our previous C90, but it always had the "getquery" bug.

One further change needs to be run on our machine after running
configure.  Configure finds that our machine has NIS+, but doesn't find
the appropriate libraries (also, we may not have all of them
installed).  Since we do not run NIS+, but just NIS, I just commented
out that NIS+ exists.  A minor point is that Configure somehow finds
-ldir, but it never finds it when linking (gets a CAUTION).  Builds OK,
though.

One other point which is likely a problem with UNICOS 9.0.xxx's make is
that I can do a "make -n" in the top-level directory and it says
everything that it will do, but when I run "make" it cd's to Src and
says it will make "FORCE" but then doesn't execute any commands.  I end
up having to cd to Src myself and run make, which then works.

I do not subcribe to this list.  Thanks for all of your work and for a
great shell.
