[PATCH] Fix compiler errors on MinGW-w64 due to identifier collision with macros.

[Liu Hao <lh_mouse at 126 dot com>]

The attached patch was generated by running the following command in GCC 
source tree cloned from git://gcc.gnu.org/git/gcc.git :

-----------------------------------------------------------
$ git checkout gcc-7-branch
$ nano libstdc++-v3/doc/xml/manual/appendix_contributing.xml
  # Append the following three lines after 'MS adds:' '_T'
  #       __in
  #       __out
  #       __inout
$ sed -i -r 's/\b__(in|out|inout)\b/__arg_\1/g' `grep -Erl 
'\b__(in|out|inout)\b' libstdc++-v3/{include,config,src,testsuite} | 
sort -u`
$ git commit -s libstdc++-v3
$ git format-patch HEAD~1
-----------------------------------------------------------

So far I have bootstrapped GCC 7.1.1 for {i686,x86_64}-w64-mingw32 with 
C, C++ and LTO enabled. Please test other languages.
