GCC has a bug [1] that does not allow to specialize templates
outside of a namespace.
An attempt to build the test results in the following error:
tst_manualqdatastream.cpp:18:15: error: explicit specialization in
non-namespace scope ‘class tst_QDataStream’
Fix it by converting the template specializations into simple function
overloads.
