[PATCH 0/2] BZ#10375 fixes

[Roland McGrath]

I took a crack at this one from Carlos's fix-me-soon list.
These changes are on the roland/bz10375 branch.

With these fixes, I can build x86_64-linux-gnu on Ubuntu 10.04
with its stock system compiler (4.4.3-4ubuntu5.1), which does
both of these inane things.  Previously I was always passing
CPPFLAGS=-U_FORTIFY_SOURCE and CFLAGS='-g -O2 -fno-stack-protector'
to configure.

The second one seems especially fragile, but I don't know of a better plan.
It certainly needs to get some more testing on a wider variety of machines
and compilers before I'll feel sanguine about merging it.


Thanks,
Roland
