Yes, I missed to add java maintainer and the patch here.
I noticed, while trying to build libjava for x64 windows, that the
configure script fails to generate link to
'libjava/gnu/java/security/jce/prng/natVMSecureRandomWin32.cc'. This
file isn't existing.
The attached patch fixes this. The implementation is straight forward,
but works for win32 api. The random value generation could be improved
here.
ChangeLog

* gnu/java/security/jce/prng/natVMSecureRandomWin32.cc: Implementation
for native win32.
Tested for x86 and x64 mingw targets. Ok for apply?
Cheers,
Kai
