allow building with VC10 (VC 2010)
Visual C++ 2010 is in public beta, so we should make sure that everything compiles with it. Needs some simple configure changes, and maybe a few other things.
I already added a start-msvc10.bat to the mozilla-build repo: http://hg.mozilla.org/mozilla-build/rev/ad3bd5686474
Separate bug for jemalloc support?
Not sure, I'll see if I get around to it. If I --disable-activex the build completes with just two patches, I'll attach them shortly. The ActiveX bits will need more work, they're full of junk like this: http://mxr.mozilla.org/mozilla-central/source/embedding/browser/activex/src/plugin/StdAfx.h#53 Which the headers that come with VC10 refuse to accept. (They want _WIN32_WINNT to be at least 0x401.)
VC10 complains about the usage of the bitset(0) constructor, saying it's ambiguous between bitset(char*) and bitset(int). The Microsoft docs (as well as other STL docs online) say that the empty bitset constructor initializes all bits to zero, so this should be functionally equivalent.

The configure changes are straightforward. The build/win32 changes are mostly straightforward, but I also unwrapped a shell loop into a $(foreach) while there. VC10 dropped support for -OPT:NOWIN98 as a linker option, so I've just unilaterally dropped it from config.mk. From reading the docs it doesn't sound like it has ever done anything useful for us anyway.

Could I also talk you into making the appropriate change at: http://hg.mozilla.org/mozilla-central/file/6de44a2c2945/tools/trace-malloc/lib/nsWinTraceMalloc.cpp#l55 so that trace-malloc works?
Looks easy, I'll get that in a followup. (I still want to fix the ActiveX stuff too, and maybe jemalloc.)
> + CXXFLAGS="$CXXFLAGS -Zc:wchar_t-" I'm going to remove this. (see bug 508905.) Could you omit this from settings for new compilers?
Pushed those two patches to trunk: http://hg.mozilla.org/mozilla-central/rev/ceef8a5c3ca1 http://hg.mozilla.org/mozilla-central/rev/27937722da69 Masatoshi: oops, I didn't remove that. Sorry! Feel free to remove it with r=me.

From bug 130372 comment 33, I would say it doesn't hurt to keep it for non-VC10 builds. Then, why not update the other occurrences too? http://mxr.mozilla.org/mozilla-central/search?string=nowin98&case=1&find=/config.mk
I don't care to support it, so it's gone. I didn't bother removing it from that other location probably because I just didn't notice it. Should probably remove that one too.

bug 559537 got filed on the ActiveX stuff in the meantime, so let's call this fixed enough. Should still fix comment 6, and file a followup for jemalloc support.

Filed bug 563316 about jemalloc support.
Ted Mielczarek [:ted, :luser]: I did not try, but I guess the line 3 of the start-msvc10-x64.bat file is probably not right: SET MOZ_MSVCVERSION=9 Should'n it be SET MOZ_MSVCVERSION=10 ?
Yes, Mitch pointed that out and I fixed it: http://hg.mozilla.org/mozilla-build/rev/8b587e01ca0d (I don't think that value is actually used anywhere anyway.)
Bug 585227 has been filed (not by me) for mozilla-1.9.2, mozilla-1.9.1 support.
