cl: on failure - there is no shell error code returned with cygwin-3.5.0-1

[Satish Balay]

Usage: Invoke 'cl' from cygwin/bash. i.e:

- run 'Visual Studio CMD' to setup MS compilers in dos shell
- run 'c:\cygwin64\cygwin.bat' [or 'c:\cygwin64\bin\bash --login']
- run 'cl /c test.c'

With cygwin upgrade to 3.5.0-1 - I'm not seeing "error return codes" on compile failures.

However - this works again after downgrading to 3.4.10-1.

Note: This works with 3.5.0-1 - if I use 'mintty' - instead of 'cygwin.bat' or 'bash --login' from 'Compiler CMD'

Perhaps a bug in current cygwin release?

thanks,
Satish
