From 510d08bfe4a24d8d4f2b5ff8df0874746a16cfe8 Mon Sep 17 00:00:00 2001 From: Fred Drake Date: Mon, 14 Aug 2000 02:50:21 +0000 Subject: In the section on the "Very High Level Layer", address concerns brought up by Edward K. Ream about FILE* values and incompatible C libraries in dynamically linked extensions. It is not clear (to me) how realistic the issue is, but it is better documented than not.
