earlier gcc version installation

[Jyh-Shyong Ho]

Dear Cygwin users,

I have a program which I compiled with gcc/gfortran in a Cygwin/CygwinX 
environment several years ago, however, I am not able to build the same 
program with the gcc/gfortran (4.9.2) in the latest version of 
Cgywin/CygwinX.  I tried to install the older version of gcc/gfortran 
(4.6.x) on the current Cygwin/CugwinX so I can build my program again, 
but I have not been successful.

I wonder if it is possible to build an older version of gcc on the 
current Cygwin environment?  Installing version 5.1.0 of gcc on the 
current Cygwin seems OK.
