Cannot build project on Cygwin

[Vaijayanti Korde]

prep2010.cmd FBTestPlugin fails to build on cygwin whereas it builds seamlessly on windows (DOS prompt).

The following is the error message:

     [exec]   1>C:\Program Files
     [exec]   (x86)\MSBuild\Microsoft.Cpp\v4.0\Platforms\Win32\Microsoft.Cpp.Win32.Targets(147,5):
     [exec]   error MSB6001: Invalid command line switch for "CL.exe".  Item has already
     [exec]   been added.  Key in dictionary: 'tmp' Key being added: 'TMP'

I went through the MSDN blogs, http://qa.social.msdn.microsoft.com/Forums/en-IE/msbuild/thread/06881761-5586-43a8-8c2f-6e54994792c6. I also tried removing TMP env variable to avoid any duplicate env entries (though env variables are case insensitive), but it didn't work.

On DOS prompt the project builds as expected whereas on cygwin it gives the above error.
Has anyone encountered such problem in the past?

Thank you.

Best Regards,
Vaijayanti

I run the prep scripts from a cygwin prompt all the time, and I have never had any issues like this.  Wish I had any ideas for you :-/

Cygwin adds environment variables 'tmp' and 'temp' (those are different from Windows variables). I noticed that caused some problems recently, maybe a new Cygwin update?  Try to disable those variable in /etc/bash.profile and i will work again.
