I agree, that it will be better.  The only problem left is when both
versions are present.  The first one found will be used, which is
probably not what the user wants.

Just because I'm not an elisp expert :)
My thought was about evaluation of (if ...).  If the list is simply
extended with DJGPP libc reference then nothing special is needed.

DJGPP version can have something like djgpp-info-lookup-symbol-alist
prepared for use with DJGPP version of libc.info.  Users will load
file with this symbol and evaluate (setq info-lookup... djgpp-info...)
This way user can choose between GNU and DJGPP versions.
