[Gcl-devel] reader and .

[Matt Kaufmann]

Hi --

I may have mentioned this before, but maybe it's worth a new mention
even if so.

A very recent CVS GCL 2.6.8pre still seems touchy about following a
dot with readtime conditionals.  An example of an unfortunate error is
below, followed by two similar forms that do not cause an error.
