The problem is temacs either doesn't set exec-path or it sets it=20 to nil =E2=80=94 I'm not sure which. There's a bug in call-process that p= revents=20 it from working correctly even for absolute paths when exec-path is nil.=20 The bug comes from the for loop in openp(), which requires at least one=20 iteration to successfully resolve an absolute path (so *any* non-empty=20 exec-path list will do). This combination of issues makes it appear that temacs can't run=20 subprocesses, but it really just needs some help.
