Don't force uppercase environment when started from a non-Cygwin

process. Except for certain Windows and POSIX variables which are
|
|
always uppercased, preserve environment case. Switch back to old
|
|
behaviour with the new CYGWIN=upcaseenv setting.

Different Cygwin installations in different paths can be run in parallel
|
|
without knowing of each other. The path of the Cygwin DLL used in a
|
|
process is a key used when creating IPC objects. So different Cygwin
|
|
DLLs are running in different namespaces.

Each Cygwin DLL stores its path and installation key in the registry.

This allows troubleshooting of problems which could be a result of
|

having multiple concurrent Cygwin installations.
