Christopher Faylor 16dc3c95fb * environ.cc (rawenv): Make this variable a file-scope static.
(getearly): Rename 's' variable to 'len' since 's' is used fairly consistently
throughout cygwin as a string variable.  Remove rawenv declaration.  Perform
other minor cleanups.
(environ_init): Remove rawenv declaration.  Only set rawenv to
GetEnvironmentStrings() if it has not already been set.  Properly free rawenv
in all cases.
