NSPR and 64 Bits

Hello everyone, 

what is NSPR's strategy concerning 64-bit technology? 

I know, it compiles and runs on 64-bit platforms, I've tried that myself.
But some compilers, e.g. Microsoft Visual Studio 2008, issue warnings when
I try things like

void * myPointer = PR_Malloc(sizeof(myStruct));

The warning is absolutely legitimate because the output of sizeof, which has
64 bit length, is casted to a PRUint32, which of course has 32 bit length. 

Throughout NSPR, most often PRUint32 is used to declare sizes of things
instead of PRSize. On 32-bit platforms, this is not a problem, because
PRUint32 and PRSize are the same. But on 64-bit platforms, they are
different, causing potential for buffer overflows. 

Are there any plans to adapt/extend the NSPR API and provide functions that
use PRSize to specify the size of things? 

Kind regards,
Stefan Birrer
