buildbots

several things:

1) gcc 4.2.1 was released recently, should be worth upgrading to.
2) mingw-4.3.0 is failing due to some boost stuff.
3) maybe upgrade boost? Auswaschbar once committed a revision that failed to compile in the buildbots and with native mingw because ptr_map had its iterator interface sanitized.

I prefer to keep using normal debian testing packages (which is the OS of the server it runs on), and not start compiling everything myself unless absolutely necessary.

Mingw-4.3.0 is probably failing because of a bug in GCC 4.3.0 (Note that it is a development version of GCC, only recently gone to stage 2 of development, and it still has over 170 regressions.)
Just ignore it until it works again.
(it started failing after I updated it)

[imbaczek]

Ok, waiting eagerly then.

I actually took a minute to look at the GCC 4.3 issue and it happens to be a known GCC 4.3 regression: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32596

I thought the latest mingw32 was 5.2?

[imbaczek]

that's the version of the package. gcc used is still 3.4.5. There's a release candidate 4.2.1, which I use, but it has slight issues.

GCC 4.3 works again but Spring now fails to compile on GCC 4.3:

I'll look at these sometime later unless someone fixes them earlier.

[imbaczek]

omg. 4.3 is so pedantic it hurts.

[Tobi]

Builds again now. I'm not sure how the template thing would need to be fixed correctly (or whether it's a GCC 4.3 bug) but I just commented out the code since it appeared not to be used anywhere.
