Re: [Gcl-devel] Build fixes for 32 bit Ubuntu Linux 11.04

[Camm Maguire]

Greetings, and thanks for the patch.

I think the -fno-stack-protector is dependent on the security model of
the running kernel.  True?  Perhaps you can describe the conditions
under which this is required.  If this is a runtime instead of compile
time issue, i.e. like the disabling of sbrk randomization we must
check for on every startup, then I think this should be handled
differently to preserve the ability to move images across different
systems.  The rest is all good -- thanks so much!, and will go in
asap. 

Take care,
