Subject:	developing 32-bit and 64-bit in a shared environment
Date:	Wed, 25 Jun 2014 13:04:24 +0000
Message-ID:	<0D835E9B9CD07F40A48423F80D3B5A702E7D8188@USA7109MB022.na.xerox.net>

I have happily been using 32-bit Cygwin for years, developing 
shell/perl scripts and C/C++ software. Some of the users that 
I support have upgraded to 64-bit Cygwin, and so my 32-bit C/C++ 
binaries no longer work for them. That has forced me to adopt 
64-bit Cygwin, which I've installed on the same machine as my 
32-bit Cygwin. I need to maintain both environments in parallel.

Now, I want to share my Cygwin $HOME directory between the two 
environments.  I already keep my binaries in $HOME/bin/$(arch) 
and $HOME/lib/$(arch), so they are covered. And, of course 
/usr/bin has to continue to point to the separate Cygwin 
environments. 

I didn't see what I was looking for in the FAQ or User Guide, 
so am looking for advice from the list.
