Description Hoang Nguyen CLA 2017-09-30 02:00:46 EDT 
I installed Cygwin64 and Eclipse to code in C++.  It worked fine previously, except 'to_string' was never resolved.  I re-installed Cygwin64 with GCC 7.2.0.  To my surprise, now even 'cout' does not resolve.  I tried all things I could, but none worked.  Out of the blue, I go to:

Project -> Properties -> C/C++ Build -> Toolchain Editor -> Current Toolchain

I switch from Cygwin GCC to MinGW.  Everything compiles.  Then, I switch back to Cygwin GCC.  Everything compiles.

Not sure what magic happens there, but this behavior is really pushing me away from Eclipse.
