Be careful, glibc uses some alignment tricks itself, so compiling it with
-malign-double or -mstack-align-double will (unfortunately) break it in
subtle ways.

No, but 2.0.7 is easy to find, you can use ftpsearch for example
(ftpsearch.lycos.com)

In theory there is more bad code in the kernel (much more), but that bad
code does result in miscompield code only rarely.

No, neither 2.1 nor 2.0 are safe, 1.1.1 is just not warning about these
problems, and might generate working code "sometimes" or even often, but its
not my system that crashes.
