Comment (by leif):
FWIW, with vanilla GLPK 4.55, `CFLAGS=-flto` works for me with GCC 4.7.4,
but fails with GCC 4.9.1 (both with binutils 2.22).
There've been major changes to LTO over time IIRC, so while the "new"
errors are annoying, they're probably not too surprising.
But it's a minor issue anyway, and apparently meanwhile modifying `CFLAGS`
is sufficient to get around the failure, as opposed to modifying the
sources which previously was necessary.

Will your "spkg" be based on my previous one? (Unfortunately my home
directory is no longer accessible via HTTP, so you'd have to use `scp`
instead, say.)
