fyi, the makeinfo bug is caused by a (undocumented of course) bug in Win32
Here's what David Korn says when it showed up in UWIN as well:
Yet some more bizarre undocumented win32 behavior. If you call the
Win32 ReadFile() function with size greater than 32K, and you are
at the end of file, it does not return successfully with 0 bytes as
you would expect, but fails with ERROR_NOACCESS.
This should be fixed in the runtime, but I have to find a reliable way
to detect this (since we have to differentiate between this buggy
behaviour and other legitimate causes of ERROR_NOACCESS).
