PATCH: Cygwin compilation

[Peter Stephenson <pws@xxxxxxx>]

This fixes up some exported data symbols to stop dllwrap complaining
that it had to work it out for itself, although it got them right.

One case where the version of dllwrap I have (2.13.90) didn't get it
right is that when it linked modules against zsh.dll it somehow missed
the last function symbol in alphabetic order, in this case zwarnnam, and
thought it had to import that as a data symbol, with catastrophic
results.  I confirmed this by adding a dummy exported function
zz_plural_z_alpha, which fixed the problem.  Has anyone else encountered
this?  Maybe Christopher is lurking.

One exported data symbol I haven't fixed up is the carefully named
global variable `c' in zle_main.c.  Apparently this needs to be exported
so that complist.c can see it (in msearch(), not to be confused with a
zillion other uses of the variable name `c' in that file).  I haven't
fixed this because I'm desperately hoping for someone to tell me it's
not true.
