POSIX simply says that readdir() returns pointer to a structure that
contains a member named d_name, which is guaranteed to be null terminated
string; the length is unspecified, but no longer than NAME_MAX. Given
this specification, how is the Mingw behaviour not correct?
If you can provide a testcase, we'll of course look at it. I'm assuming
that you're not messing with d_name directly, but rather having problems
using readdir(). Any code that directly modifies `struct dirent' is non
conforming, and that's not something we can do anything about.
Regars,
