Forum: Ruby-core Kernel.exec doesn't respect COMSPEC environment variable on Windows

Unfortunately, I've lost my topic branch for this issue, so have to 
rewrite from the previous patch again.

 Here is pretty convoluted test case:

 puts ENV["COMSPEC"] # => "C:\WINDOWS\system32\mycmd.exe"

 File.open("1.bat", "w") { |f| f.write("time") } # create test batch 
file with command which waits for user input

 Kernel.exec("1.bat") # now the process tree inspection shows that the 
"C:\WINDOWS\system32\cmd.exe" is still used to interpret 1.bat
