When I tried to review the linux kernel on Windows in my laptop and incidentally found that it failed to open the aux.c. And Microsoft tells me: (http://msdn.microsoft.com/en-us/library/aa365247.aspx) > Do not use the following reserved names for the name of a file: > CON, PRN, AUX, NUL, <snip...>, and LPT9. Also avoid these names > followed immediately by an extension; for example, NUL.txt > is not recommended. The name "aux" is listed above. And it sometimes makes sense to review linux on windows, so we rename the aux.c to auxiliary.c.
