Thank you for the suggestion.  I found the compiler manual at
http://www.nag.co.uk/nagware/np/r52_doc/index.asp
and I kind of wonder whether the -Wl,-Wl,, in your change is a typo.
Shouldn't it rather be
          _LT_TAGVAR(lt_prog_compiler_wl, $1)='-Wl,'

?

Also, I would like to ask you to submit test results for this compiler,
so that we know how well we support it.  If you have version 2.2.10,
please build and test like this:
  ./configure F77=nagfor FC=nagfor CC=gcc CXX=no GCJ=no
  make -k all check

and send all output, plus tests/testsuite.log, gzip'ed.  That way we can
also fix things that we see are lacking.  You might want or need to use
FC='nagfor -f95' or so.

If you are interested to help, some of the Fortran macros in Autoconf
could be improved for nagfor as well, trying to find it, and setting
some of the flags.  I can cook up a patch if you're willing to test it.

Thanks!
Ralf
