[lmi] Installing cygwin under wine--failure

[Greg Chicares]

I've spent some hours trying to install current 64-bit cygwin
under wine. I'm not optimistic. This is one of many reports
of failure:
  https://bugs.winehq.org/show_bug.cgi?id=40528
but here I'll present what I've tried.

I started a wine console thus:
  wineconsole cmd &
and copied the files specified in 'INSTALL':
  copy Z:\cache_for_lmi\downloads\setup-x86_64.exe C:\cache_for_lmi
  copy Z:\opt\lmi\src\lmi\install_cygwin.bat C:\cache_for_lmi

At first, the cygwin installer refused to run under wine due to
an incorrect msw version. I used 'winecfg' to change that:
  add application 'setup-x86_64.exe'; "Windows Version" 10
and got past that issue.

Then I ran the next commands in 'INSTALL':
  cd C:\cache_for_lmi
  install_cygwin
and everything seemed to work until the postinstall step,
although I did see this:

  017b:err:winediag:SECUR32_initNTLMSP ntlm_auth was not found or is outdated. \
  Make sure that ntlm_auth >= 3.0.25 is in your path. Usually, you can find it \
  in the winbind package of your distribution.

on the terminal from which I had invoked 'wineconsole'.

In the postinstall step, many (perhaps all) scripts failed. I found
what seem to be temporary logs such as this:
  ~/.wine/drive_c/cygwin-lmi/var/log/setup.log.runXa00303
with contents such as:
  Cygwin WARNING: Couldn't compute FAST_CWD pointer. [...]
  /etc/postinstall/automake1.9.sh: fork: retry: Resource temporarily unavailable
I killed each process that had such a fork failure--e.g., for the
log snippet above, I found the process:
  bash.exe --norc --noprofile /etc/postinstall/automake1.9.sh
and terminated it.

Then I tried running 'setup-x86_64.exe' directly (not through the
batch file), selecting "local install", and adding no further
packages. I saw this:
  AddAccessAllowedAceEx(, group) failed: 1337
on the wine console (it wasn't observed when running the batch
file, which presumably hid it). This progressed rapidly to the
postinstall step, which failed just as described above.

I also tried changing the version to msw-7 in 'winecfg', but
did no better than the attempt with msw-10 above.
