+ gcc 4.1.1 threw up.
+
+PH/03 On Solaris, an unexpectedly close socket (dropped connection) can
+ manifest itself as EPIPE rather than ECONNECT. When tidying away a
+ session, the daemon ignores ECONNECT errors and logs others; it now
+ ignores EPIPE as well.
+
+PH/04 Applied Nico Erfurth's refactoring patch to tidy up mime.c
+ (quoted-printable decoding).
