* generic/tclEnv.c:
* unix/configure.in:
* win/tclWinPort.h: putenv() on some systems copies the buffer
rather than taking reference to it. This causes memory leaks
and is know to effect mswindows (msvcrt) and NetBSD 1.5.2 . This
patch tests for this behavior and turns on -DHAVE_PUTENV_THAT_COPIES=1
when approriate. Thanks to David Welton for assistance.
[Bug 414910]
* unix/configure: regen'd
