That seems like a plan to me. I had been thinking of making
win32error.c itself log the conversions, but that would not provide any
context information. AllocateFile could log the file name along with
the code, which should be enough info to associate a particular log
entry with the actual failure.
Note you should probably save and restore errno around the elog call,
just to be safe.
Could someone with access to Windows code and test this?
