Hi, I think I found a reproduceable problem in PATH environment variable, so I'm reporting it to here. Problem description: If an original MS-DOS PATH environment variable has something like '"C:\Program Files\Test"', this part of PATH variable is not converted under Cygwin environment. However, this part in wrongly converted back when I called MS-DOS program. As a result, I cannot use _spawnXX functions correctly from my program under Cygwin environemnt if original PATH environment variable contains '"'. For example, Original PATH: PATH=C:\WIDNOWS;"G:\testdir" Cygwin PATH: PATH=/usr/local/bin:....:/cygdrive/c/WINDOWS:"G:\testdir" PATH for a program executed from Cygwin: PATH=C:\cygwin\usr\local\bin;...;c:\WINDOWS;"G;C:\testdir" Remedy: Remove all '"' from original MS-DOS/Windows PATH environment variable.
