I downloaded a nightly snapshot dated 13-9-2010 and got this error when building with Qt 4.7 from git (~11-9-2010):

compilation terminated.

sys/mman.h isn't present for a mingw toolchain... perhaps some other build steps are needed, but it seems Platform.h has changed quite a bit since I had it modified for mingw-w64... Is JIT now enabled for 64-bit Windows + GCC (mingw-w64)?

I must be honest and say that the problem I reported here, went away somewhere in September, and Qt 4.7 Webkit does not exhibit this problem.
