Hi,

These new patches seem to cause problems with building for ming (using
i686-w64-mingw32-g++):

/gdb/common/pathstuff.c: In function 'gdb::unique_xmalloc_ptr<char>
gdb_realpath(const char*)':
/gdb/common/pathstuff.c:56:14: error: 'MAX_PATH' was not declared in this scope
     char buf[MAX_PATH];
              ^

     DWORD len = GetFullPathName (filename, MAX_PATH, buf, NULL);
     ^

     DWORD len = GetFullPathName (filename, MAX_PATH, buf, NULL);
           ^

     if (len > 0 && len < MAX_PATH)
         ^

       return gdb::unique_xmalloc_ptr<char> (xstrdup (buf));
                                                      ^
make[2]: *** [pathstuff.o] Error 1

I saw this while rebuilding branch 8.1, I didn't check master.

Sorry if this has already been reported, I can't find any mention of
this problem in the list archives.

I suspect there's already a recommended way of handling MAX_PATH cross-platform.

Thanks

Christophe
