Bison 3.8.2 glr2.cc portability report

Akim,

I thought you might be interested in the results of portability testing =
for the Ox 1.10 release (available yesterday).

Ox 1.10 has 6 parsers generated by bison 3.8.2, using the glr2.cc =
skeleton.

For portability testing, I run the regression tests on each operating =
systems using each C++ compiler listed below.

The Solaris Studio errors noted below are due to a defect in support for =
the C++ 2011: a noexcept operator within a noexcept specifier for an =
overloaded version of std::swap in several header files is the source of =
the error messages above.  The exact same signature is found in the =
equivalent GNU & LLVM header files.  As an experiment (on Solaris 11.4), =
I edited the offending signature in the header files to bypass the =
problem, which allowed Ox to compile.  Ox then failed to link due to =
several versions of the C++ std::ostream '<<' operator missing from the =
C++ library.

Regards,

Tom Shields
