Bug#655518: gcc-4.6 on Alpha: incorrect code generation when, compiling git

[Michael Cree <mcree@orcon.net.nz>]

Fixed in gcc-4.6 version 4.6.2-13.  Both git and libarchive, which
previously FTBFS because of this bug, now compile and their test suites
pass.  Feel free to close the bug report.

Cheers
Michael.
