Figured something out, that I think is the problem...
Looks like the code in dumpstuff does this:
#ifdef AFS_LARGEFILE_ENV
treat offsets at 64bit
#else
treat offsets as 32bit
#endif
problem is that it's building where LARGEFILE_ENV is not true, and
64BIT_ENV is true.
It needs to be
#ifdef AFS_64BIT_ENV
treat offsets as 64bit
#ifdef AFS_LARGEFILE_ENV
support use of >32bit offset values
#endif
#else
treat offsets as 32bit
#endif
Basically, the code is currently written with the assumption that if
your client is 64 bit capable, it will ALWAYS be built with largefile
support. That assumption is not currently correct.
The attached patch appears to fix the problem with WriteFile in
dumpstuff.c, but there are likely other fixes needed elsewhere.
