I'm putting in a little time today on my windows branch of jhbuild. Running git now works (using a .bat file to call MSYSgit in its own shell, it's all messy but works fine once it's set up).
I spent the past hour or so wondering why ACLOCAL_FLAGS was being ignored. I finally realised that it's not actually honoured by aclocal at all and never has been. autogen.sh scripts tend to execute aclocal $ACLOCAL_FLAGS which make it work often enough that I assumed it was meant to.
Now I wonder whether autoreconf would accept a patch to make it honour $ACLOCAL_FLAGS, or if I should patch Pixman's autogen.sh to call autoreconf $ACLOCAL_FLAGS .. and any others that don't ..
Highlights of Glastonbury were definitely Blur, and a more obscure band called Edward II who I last saw aged about 12.
