Alex Crichton fcd99aae0a rustc_driver: Frob the global PATH less ... Environment variables are global state so this can lead to surprising results if the driver is called in a multithreaded environment (e.g. doctests). There shouldn't be any memory corruption that's possible, but a lot of the bots have been failing because they can't find `cc` or `gcc` in the path during doctests, and I highly suspect that it is due to the compiler modifying `PATH` in a multithreaded fashion. This commit moves the logic for appending to `PATH` to only affect the child process instead of also affecting the parent, at least for the linking stage. When loading dynamic libraries the compiler still modifies `PATH` on Windows, but this may be more difficult to fix than spawning off a new process.		2015-06-17 17:38:03 -07:00
