SOLVED: zsh / cygwin 1.x / status access violation

[Johannes Mähner <johanm at camline dot com>]

Geoff Wing from the zsh mailing list gave me 
the tip to undefine HAVE_MMAP in config.h of zsh.
The question if there is a bug in mmap of cygwin or not 
serves as food for our cygwin-gurus ;-)

That's fine.  I didn't investigate whether the mmap problem was specific
to zsh or if mmap is not fully supported under cygwin.

:BTW, how did you figure out that mmap could be the problem?
:(e.g. status access violation => denied memory access => 
:check out everything which is correlated to memory ;-)

Close to that :-)  Though I suspect I just ran it from gdb to find out
roughly whether the problem was - and I have the advantage of knowing
the internals of quite a bit of zsh fairly well.
