Bug #: 29569
           Summary: mingw make complains "cp: cannot stat
                    `d3dcompiler_43/libd3dcompiler.a': No such file or
                    directory"
           Product: Wine
           Version: 1.3.36
          Platform: x86
        OS/Version: Windows
            Status: NEW
          Severity: minor
          Priority: P2
         Component: build-env

Configuring wine on mingw per the wiki seems to go fine, but 'make' fails with

rm -f dlls/libd3dcompiler.a && cp -p d3dcompiler_43/libd3dcompiler.a
dlls/libd3d
compiler.a
cp: cannot stat `d3dcompiler_43/libd3dcompiler.a': No such file or directory

There are four problems of this sort in Makefile.  Doing
  sed -i 's,$(LN_S) ,$(LN_S)/dlls' Makefile
seems to rescue it, and let it get further.

That LN_S comes from function wine_fn_config_dll(), line 414 of aclocal.m4.
There's another one that looks like it needs fixing at line 422, too.

See http://wiki.winehq.org/WineOnWindows and/or
http://kegel.com/wine/wow.html for notes on how to reproduce.

(I had to do 
  cd dlls/libwine0; make; cd ../..
  cd dlls/d3dcompiler_43; make; cd ../..
to get this far, but maybe that was operator error, not sure.)
