gcc2721b.zip didn't have gxx.exe. The gxx.exe you had was from
djdev203.zip. You can leave it alone, since the latest GCC distributions
come with gpp.exe, not gxx.exe. In any case, you lose the ability to
invoke the old GCC via gxx or gpp.

No, that won't work, since info.exe doesn't get the settings from the
[gcc2721] section.
One way to have the old Info files available is to rename them into
gcc2721.info, gcc2721.i1, etc., and then add a menu item to info/DIR
which says something like this:
* GCC2721: (gcc2721). The old GCC.
You will also have to edit the tag tables in gcc2721.info, so that they
point to the renamed files.
Thereafter, you should be able to say "info gcc2721" and get the old
manual.
Alternatively, you could move all the old files into a separate directory
without any modifications, and then read that manual with this command:
info -f /foo/bar/gcc.info
where "/foo/bar" is the absolute name of the directory where you moved
the old Info files. Note the "-f" switch: it's crucial for this to work,
since it doesn't go through info/DIR at all.
(As you see, Info doesn't cope very well with multiple versions of the
same manual installed on the same machine.)
