* 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
