Hello,

I'm using an MPI library for nagfor that has the -rpath already correctly hidden
inside $wl, unfortunately since it starts with the same letters as the
corresponding libtool option, I'm getting erroneous results:

excerpt from make output:
============8<=======================================================================

-Wl,-Wl,,/home/tjahns/opt/scales-ppm-0.0.1-i386-linux-nag52-mpich2-1.4.1-noomp/lib
-Wl,-Wl,,-rpath -Wl,-Wl,,/home/tjahns/opt/mpich2-1.4.1-nag52-i386-linux/lib
============8<=======================================================================

Thus in this example

-Wl,-Wl,,-rpath,,/home/tjahns/opt/mpich2-1.4.1-nag52-i386-linux/lib

is replaced with

-Wl,-Wl,,-Wl -Wl,-Wl,,"" -Wl,-Wl,,-rpath -Wl,-Wl,,""
-Wl,-Wl,,/home/tjahns/opt/mpich2-1.4.1-nag52-i386-linux/lib

I'm not sure of the best way to address this unfortunate coincidence of compiler
and libtool flags. My, perhaps naïve, idea would be to test whether an argument
starting with -Wl, also matches $wl and, in case $wl does not equal "-Wl," pass
the flag argument on to the linker unaltered.

I'm using libtool 2.4.2 and nagfor 5.2.721. I can provide further information on
the software environment if desired.
