+
+ * redhat (v?) graphical install bomb-out?
+
+ * egcs-1.03 ice: stem.cc:327; should localize bug (mine's still 10K)
+
+ * gcc 2.8.1: see ice and RESIZE_ICE
+
+ * xdvi: PS in magnifying glass.
+
+ * GNU diff 2.7: diff -rN does not see a new directory with empty file
+
+ * GNU patch 2.1: <must find simple example> if patch chokes on a
+ hunk, or on allegedly unsorted hunks in a diff, it may stop
+ without a trace of failure (create .rej file, print error or
+ dump core) and just ignore any further diffs.
+
+ * glibc 2.0:

+ - etc.
+
* grace notes
- - adapt for multiple font sizes.
