Failed to read temp file under Windows

[elemel21]

When I start gvim on Windows 7 I get an ugly warning:

vim-misc 1.8.1: Failed to read temporary file (C:\Users..\Local\Temp\VIAFE50.tmp) with standard output of external command:
Vim(return):E484: Can't open file C:\Users..\Local\Temp\VIAFE50.tmp! (external command: uname).

Could you add an option to switch this file creation and check off or at least setting a path to the temp file?

Narrowed down it results is these lines:

  let result['stdout'] = s:readfile(tempout, 'standard output', a:options['command'])
  let result['stderr'] = s:readfile(temperr, 'standard error', a:options['command'])

where this error is caught:

  call xolox#misc#msg#warn("vim-misc %s: Failed to read temporary file (%s) with %s of external command: %s! (external command: %s)", g:xolox#misc#version, a:fname, a:label, v:exception, a:cmd)

In xolox/vim-easytags#58 I was working on uncovering a serious bug in external command execution on Windows. During my analysis I added the warning message; the fact that the message was printed only confirms the fact that the bug existed. However that bug should be squashed in vim-misc 1.8.3 which I just released. Thanks for the feedback and happy Vimming!
