Sorry, I uploaded incorrect file.
If the line 278 of lauxlib.c is "&& errno == 0", download the file
again or replace == with !=.

Thank you. I patched 5.4 work1 by accident but got away with it! There are also a few places in you files that are "initb" instead of "init.b". My kids are flanking me, I don't have time to produce a patch. I'll add that to my up-coming WinLua release. 

sorry, output from my tests:

#patched 5.4 lua test build
