The patched version uses execve, the unpatched version doesn't.
Long ago, it made sense to avoid execve, because some pre-POSIX
platforms lacked execve. (The FreeBSD man pages say that
execve was introduced in 4.2BSD, so I assume 4.1BSD lacked it.)
execve was standardized in POSIX 1003.1-1988, though. It's
safe to assume execve now on all POSIXish platforms, and doing
so simplifies Emacs a bit.
