IIUC, you are:
1. compiling TXT -> RES
2. creating a list of all the RES files generated
3. passing this list to the bundling program

This is similar to the response file concept used in the msvc and cw
toolsets. There was a bug in the old logic that meant that the response
files weren't getting regenerated. I suspect that this is where your
problem lies.

If you download the latest CVS version of jam_src, you can do the following:

nl = "

action bundle
    $(BUNDLER) ... @($(TMPFILE):S=.lst:E=$(nl)"$(<)")

The @(...) is the new response file logic...
   $(TMPFILE) -- generate a temporary file (don't care what it's called)
   :S=.lst -- make it have the .lst extension (i.e. it matches *.lst)
   :E= -- set the content of the file to...
   $(nl)"$(<)" -- a list of newline separated source files

the @(...) will expand to the name of the file, e.g. /tmp/jam124890.lst.
