The value of name coming in, that's a relative file name that will be searched for on the @INC list?

if (strcmp(name + len - 3, ".pm")) { Should be _stricmp, since it might be ".PM" etc.

Also, what if the name's length is less than three?

sizeof char is 1, by definition.

This will warn any time a .pm file doesn't define a package with the same name, so its applicability is not just Win32 case differences. It can be more generally useful, as I mused in another message.
