Hi again,
well the second issue is a bit more clear now. It is because I do like
this:
printf("%"FMT64"d %"FMT64"d", sec,usec);
for some reason the second argument is shown as 0, though it is not 0.
I guess I need to go deeper in preprocessed code.
but the first one still remains:
1. this is always falling back to BDOOR_CMD_GETTIME case. Why? Is my
WMWare too old?
