Patch for xtradb compilation on visual studio

[Kristian Nielsen]

Here is a patch for XtraDB (from Percona Server 5.5.17-rel22.1).

We needed this in MariaDB 5.5 to compile on Windows. The problem is that this
compiler apparently does not like having #ifdef inside macro invocations.

I thought Percona might want to include it upstream, in case there are other
compilers that also do not like this.

Kristian -

Thank you, I have added it to

where we track Windows compilation errors.
