Jens Geyer resolved THRIFT-4940.
--------------------------------
Resolution: Not A Problem
GetFullPathName() will set the values on success and the caller is advised to
not use the values on error return. This is a common Windows API pattern, I
don't think adding any initialisation code will improve anything. Thou shalt
not use invalid data, period.
Only "maybe" point of discussion here is the basename argument, as this one is
documented as "can be NULL" and it is not used anyway. OTOHJ, never change a
running system unless you have a good reason ...
> value should inialization when defined
