Re: [ros-dev] [ros-diffs] [dgorbachev] 26483: Undo r26482 change, waste more stack space.

1) 64-bit pointer bug: I asked Thomas to make a test-case and submit it. I
don't know if he has.
2) Pragma support: GCC doesn't view msvc-compatibility as a priority.
3) -mrtd: Has been fixed and re-broken countless times. This is an example
of one of them: 
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=9601. Still present in 4.2
4) One of multiple Vista bugs:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30335.

There's also the fact that 4.1.2+ are unusuable on -j2 or more because they
incorrectly map PCH files, so our build server is forced to use 3.4.5, which
is incompatible with KJK's new PSEH. 4.2 is also incompatible with PSEH due
to other, newly added exciting bugs.

If you point out the bug numbers in question I'd be happy to pester
the gcc team. I won't file a bug report for these issues as I don't
know enough about them but get me a list with bugzilla IDs and I will
at least spam them for a while.
