The attached patch fixes a compiler warning on MinGW64
../../../../../build/gcc/src/libgfortran/io/unix.c:51:0: warning: "lseek" redefined [enabled by default]
which is due to MinGW64 now supporting LFS. (Seemingly, using a similar define as libgfortran.) The following patch should fix the issue.
Thanks for Kai for suggestions and testing the patch on MinGW64. The goal is that it also works with older MinGW64 and with 32bit MinGW, but that has not been tested ...
OK for the trunk? Tobias
