Thank you for your prompt reply to my inquiry.  In the process of
documenting the steps I go through, I discovered the cause of the problem.

I started from scratch, unzipping TXI390B.ZIP and GCC2721B.ZIP into a
temporary directory, and manually setting the INFOPATH variable, so that I
could document exactly what I had done, and, lo and behold, it worked!

I went back to the normal installation directory, and finally discovered
the problem was that I had set the INFOPATH variable as follows:

   INFOPATH=c:\dj201/info

instead of

   INFOPATH=c:/dj201/info

Somewhere in the changes between TXI360B.ZIP and TXI390B.ZIP, the INFO.EXE
program became sensitive to backslashes vs. forward slashes.  The reason I
had this mixture of forward and backslashes was that I was using a big
batch file to set which version of DJGPP to use (I can switch between
1.12, 2.00, and 2.01 from the command line).  The batch file had lines in
it such as this:

   if "%1" == "112" set DJDIR=c:\dj112
   if "%1" == "200" set DJDIR=c:\dj200
   if "%1" == "201" set DJDIR=c:\dj201
   if "%DJDIR%" == "c:\dj112" SET INFOPATH=%DJDIR%/docs;%DJDIR%/docs/djgpp
   if "%DJDIR%" == "c:\dj200" SET INFOPATH=%DJDIR%/info
   if "%DJDIR%" == "c:\dj201" SET INFOPATH=%DJDIR%/info
   PATH=C:\DOS;C:\BAT;%DJDIR%\BIN

I wanted to use the DJDIR variable to invoke executables from other batch
files, like this:

   %DJDIR%\bin\INFO %1 %2 %3 %4 %5 %6 %7 %8 %9

which of course doesn't work with forward slashes; but I can get around
this problem with a little extra work:

   if "%1" == "112" set DJDIR=dj112
   if "%1" == "200" set DJDIR=dj200
   if "%1" == "201" set DJDIR=dj201

   ...

   c:\%DJDIR%\bin\INFO %1 %2 %3 %4 %5 %6 %7 %8 %9

I don't know if there is a lesson to be learned here or not, but I see now
that I have approximately 20 batch files to change.  Argh.
