If there is indeed interest in osmesa on Windows, we should instead
integrate src/gallium/targets/osmesa into SCons.
Afaict the Octave people still use it. There was a guy in #dri-devel
who was having issues with the Windows build not too long ago [1]
Iirc the VTK folk are were using osmesa, although I'm not sure if (how
much) Windows support is a thing for them. Hence the presence of the
scons build.
All of that is more of jfyi rather than feeling sentimental about nuking it :)

Thanks for the info Emil.
The osmesa I removed from scons was the one with classic sw rasterizer.
The osmesa w/ softpipe/llvmpipe is in src/gallium/targets/osmesa , but
was never integrated into scons build (just autotools.)
I'm OK adding support to build osmesa on Windows with llvmpipe/softpipe,
but I don't think there's value in supporting the classic rasterizer --
less code that we need to worry about MSVC portability. I might give it
a go when I find some time.
For the record, there was a point in time where I wanted SCons to build
most of Mesa in the hope of replacing autotools, which is why scons
build more than just Windows. But it's a loosing battle. Nowadays I'm
more interested in reducing the SCons scope as much as possible, so
there's less stuff for me and everybody else to maintain.
(And if there's a build system that could really work across multiple
platforms and make everybody happy, my bet would not be scons, but
rather cmake. But I doubt there will ever be agreement or time to take
such enterprise anyway.)
