Please excuse me for taking so long to reply, I have been too busy to get
to it this week.

The following orchestra works fine with DirectCsound 2.5 and 2.6 (on
Windows 95), but produces only a steadily pitched tone with Consound 3.51
and Winsound 3.51 (the test MIDI file is just one long note, during which
I added some pitchbending--I can send the MIDI file by attachment to the
list or directly to you if you would like to see it).

sr=44100
kr=4410
nchnls=1

 instr 1
kpch pchmidib  12
asig oscil 10000, cpspch(kpch), 1
 out asig
 endin

;score
f1 0 4096 10 1
f0 25

This next orchestra (with same score and MIDI file, all of the versions of
Csound listed above) results in a jump of several octaves in pitch each
time there is a new pitchbend message. Am I doing something wrong (I
wouldn't be surprised)? Is pchbend supposed to work this way?

sr=44100
kr=4410
nchnls=1

 instr 1
ipch pchmidi ; translate MIDI note number to pch
kbend pchbend 4 ; get pitchbend messages and scale them to range of 0
through 4
kpch = ipch + (kbend-2) ; shift pch value of note by value of kbend (range
of -2 through 2)
asig oscil 10000, cpspch(kpch), 1
 out asig
 endin

I hope this at least partly answers your question.
