Over the weekend, cygwin also added fexecve and execvpe.  Is it worth a
gnulib module for execvpe that does (roughly):

char **saved_environ = environ;
environ = env;
int result = execvp (file, argc);
environ = saved_environ;
return result;

or will that misbehave in the case where the env argument contains a
different PATH than the current environ?
