[Octave-bug-tracker] [bug #54237] 'abs' function template hack in pr-output.cc is not portable

[Mike Miller]

Follow-up Comment #3, bug #54237 (project octave):

I am still bewildered as to how the compiler is attempting to match  the bare
function name 'abs' against various 'std::abs' definitions.

The only thing I can think of is that the argument to 'abs' is resolved as a
namespaced 'std::int32_t' for example, instead of a bare 'int32_t' type, which
allows the compiler to resolve functions on it in the 'std' namespace. In the
Octave source code itself, we don't use 'std::int32_t' anywhere, but maybe
some difference in the Solaris system header files is making that equivalence.
