[Bf-committers] Windows Debug Build (possible with free tools?)

[Campbell Barton]

Can any free tools build python32_d.dll ?
MinGW and MSVC2010 are both not supported and no support is planned
for either (reading the python ML).

Anyone tried to build debug python3.2 debug on MSVC Express 2008?

No luck finding this info here: http://docs.python.org/devguide/
