If you apply this patch and have wordcode files, you have to build
them anew, because the header format has changed slightly. zrecompile
will not be able to detect this.

Here is the patch for zcompile. If neither is given, the setting of
KSHAUTOLOAD at the time of loading is used to determine how to load
the function.
I haven't added that for autoload yet and there is another thing:
loadautofn() should probably make use of this too, maybe execute the
Eprog it gets from getfpfunc() when it knows that the function should
be ksh-autoloaded (either because the dump file said so or because
`autoload +x' said so). But then, it doesn't do that if KSHAUTOLOAD is
set. I guess that's some security issue?
Bye
