Hi Guys
I am applying the patch below to extend the linker's error message
when it fails to find a library, but there is a file present in the
search path which matches if the "lib" prefix were to be ignored.
Cheers
Nick

* ldfile.c (ldfile_open_file): If a search for a library fails,
but there is a file that would match if it had a "lib" prefix to
its name, then tell the user.

s/use use/use/ I presume here.
Can you please match the heading of the change committed with the subject
of the corresponding message sent to the mailing list (as `git am' would)?
It will make it easier to chase any discussion corresponding to a commit
when someone does repo excavation in the future.
