So that setup did produce exes and ran through to completion. There were
some linkage warnings throughout the build:
c:\python27\include\pymath.h(22) : warning C4273: 'round' : inconsistent
dll lin
kage
But lldb still ran, I could load an image (tried 'image create
c:/bin/ninja', and it correctly told me it was an i386 image), and that's
about it.
For reference, it took just under 14 minutes to build on a 24 core Xeon
running at roughly 3.8 GHz, using an OCZ RevoDrive X3 SSD raid and 48 GB of
RAM.
Trying that non-Python config patch now.
