[John Donoghue]

Follow-up Comment #33, bug #57644 (project octave):

Posted to gnulib at
https://lists.gnu.org/archive/html/bug-gnulib/2020-01/msg00146.html

its an issue with gnulib, but effects mingw/windows only.

They have posted as suggest fix already, which is somewhat similar to what I
posted in comment 19.


diff --git a/lib/lseek.c b/lib/lseek.c
index 013f665..b249839 100644
--- a/lib/lseek.c
+++ b/lib/lseek.c
@@ -63,7 +63,7 @@ rpl_lseek (int fd, off_t offset, int whence)
       return -1;
     }
 #endif
-#if _GL_WINDOWS_64_BIT_OFF_T
+#if _GL_WINDOWS_64_BIT_OFF_T || (defined __MINGW32__ && defined 
_FILE_OFFSET_BITS && (_FILE_OFFSET_BITS == 64))
   return _lseeki64 (fd, offset, whence);
 #else
   return lseek (fd, offset, whence);


I have tried this exact fix yet to verify, but it should work.
