I have been switching env/OS/arch/triple dependent profile and rc files
and sections for years with:
64 $ echo $OSTYPE $OS $HOSTTYPE $MACHTYPE
cygwin Windows_NT x86_64 x86_64-unknown-cygwin
32 $ echo $OSTYPE $OS $HOSTTYPE $MACHTYPE
cygwin Windows_NT i686 i686-pc-cygwin
Please note that *only* $OS is exported by default (in the above list),
so you will have to explicitly export (in profiles) any other shell
variables you wish to be available to shell subprocesses.
