t/src/warnings.t: Test fails when Parrot built with g++ and --optimize

[jkeenan]

Inspired by mikehh's testing adventures, I decided to try to configure and build Parrot on my Linux/i386 box using, for the first time, g++ for all options and optimized, i.e.:

perl Configure.pl --test --optimize --cc=g++ --cxx=g++ --link=g++ --ld=g++ --maintainer

I got one test failure which I would not (and did not) get when I simply configured on the same machine simply with:

perl Configure.pl --test

Here is the failing test:

I reported this failure in TT #1187 - some more detail there

it fails on all --optimize builds due to problems with include/parrot/context.h

I have had failures with Ubuntu 9.04 amd64, Ubuntu 9.10 amd64 and Ubuntu 9.10 i386 with both g++ and gcc with --optimize builds - the test passes without --optimize on all the platforms (both gcc and g++)

Since this issue was reported in TT #1187, I'm closing this ticket in favor of that one.
