This problem does not occur if -nostdlib isn't specified. This
suggests to me that gcc is somehow handling libgcc differently if it
is specified on the command line??
Is this my (stupid?) error or have I stumbled across a gcc bug?
What version of the GNU binutils are you using? There have been several
bugs in this area, and the fix is in the GNU linker and how it interacts
with plugins. Try using the latest development version of the GNU
binutils. If that doesn't help, file a bug report at
http://sourceware.org/bugzilla with a complete self-contained test case.

Binutils 2.21.
I will build the latest snapshot (I think it's 2.21.51 or something like
that) and report back.
Thanks,
Patrick
