             Bug #: 31429
           Summary: unimplemented function msvcrt.dll._stat64 and
                    msvcrt.dll._fstat64
           Product: Wine
           Version: 1.5.10
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: msvcrt
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: htl10 at users.sourceforge.net
    Classification: Unclassified


The latest version of R (http://www.r-project.org) is built with a slightly
customized mingw-w64 to provide win32- and win64- multiarch binaries.

http://www.stats.bris.ac.uk/R/bin/windows/base/R-2.15.1-win.exe

The toolchain is inside:
http://www.stats.bris.ac.uk/R/bin/windows/Rtools/Rtools215.exe

and described in http://www.stats.bris.ac.uk/R/bin/windows/Rtools/

Previous version of R (2.14.x) and the toolchain works okay under wine. But the
latest complains of:

(R 2.15)
wine: Call from 0x7ef79b28 to unimplemented function msvcrt.dll._fstat64,
aborting
fixme:ntdll:RtlNtStatusToDosErrorNoTeb no mapping for 80000100

and running gcc --version inside wine cmd from the toolchain, complains of:

=========================

....
======================

It is possible that this is both a code change in R (to provide 64-bit file
access on 32-bit platforms) as well as a change in the toolchain used from
mingw-based to mingw-x64 based.

Can these two unimplemented functions be implemented quickly? It is possible
such a problem will be more frequent sine it looks like mingw-w64 is gaining
ground compared to mingw, for a variety of reasons.
