[Message part 1 (text/plain, inline)]

Dear libtool developers,
here is a patch for the current libtool git repo when using the NAG 
Fortran compiler
(nagfor) to link exectuables or libraries. nagfor doesn't accept 
arguments passed twice,
but a setup in the ltmain.in does exactly this when using -openmp as a 
flag. To avoid
hiccups, I added the following patch  (below).
I would be grateful if you could push this to the libtool git repo!
Thanks a lot in advance!
Cheers,
    JRR
