Sorry for omitting that. The error was:
w32.c(3820) : error C2520: conversion from unsigned __int64 to double
not implemented, use signed __int64

Nope. Same error.
Else-thread, Stefan Monnier asked:
> Wouldn't it be better to cast to (double) ?
That doesn't help either. Each of these variations causes the same error:
totphys = (double)(memstex.ullTotalPhys / 1024.0);
totphys = memstex.ullTotalPhys / (double)1024.0;
totphys = (double)memstex.ullTotalPhys / 1024.0L;
totphys = (double)memstex.ullTotalPhys / (double)1024.0;
