Some of the settings in CYGWIN are read by cygwin1.dll only at DLL 
initialization time.  As a result, it is generally recommended that you
set CYGWIN *before* any Cygwin-dependent application runs (i.e. so that
the DLL is not loaded and the changes take affect when the next app is 
run).  This is really the only rule about how and where CYGWIN should be
set.  Feel free to set it in your control panel (on NT/W2K) or autoexec.bat
(on Win 9x's) if you want.
