[TxMt] warning: unused typedef 'serializing_int_requires_an_unsigned_type'

[Jacob Carlborg]

Since I updated Xcode to a later version (can't remember the exact one) 
I get a huge amount of warnings one at the bottom. Can we please fix 
this or suppress the warning. The amount of output this generates is 
ridiculously annoying.

2 warnings generated.
