--- Comment #26 from Bill Zissimopoulos <gnu.org at billz dot fastmail.fm> --- (In reply to niXman from comment #25) > updated patch there: > https://gcc.gnu.org/pipermail/gcc-patches/2023-January/610029.html A couple of things: 1. If the GetFinalPathNameByHandle method fails, I would always fall back to the GetFullPathName method (which has fewer failure modes). GetFinalPathNameByHandle can fail for many reasons: for example, if the drive X: is a local drive created by SUBST/DefineDosDevice or for special files like NUL (as you have discovered). 2. I would not do anything particular for special files like NUL. See my above comment: if GetFinalPathNameByHandle fails fall back to GetFullPathName.
