Comment:
I've added manpages, to document each of the changes I've made to address this
issue. In preparing examples, for inclusion in these manpages, I've also
uncovered a couple of additional defects, which I've addressed:
• Correct wchar_t to MBCS unpaired surrogate handling
• Handle wcsrtombs() initial surrogate completion
These corrections will be incorporated into mingwrt-5.3.1.

Ticket details:
I'm using MinGW-gcc-6.3.0. The wcsrtombs() function as mentioned in the docs on
cppreference should return the number of bytes that would have been written to
src. However it doesn't do so on my end. It seems the implementation doesn't
ignore the length parameter when dest is passed as NULL? A similar issue was
reported and presumably fixed for the Mingw-w64 on the sourceforge site
Currently working around by passing INT_MAX as the length parameter, so it
finishes within the limit and returns the size.
I apologize in advance if this is just an issue from my end or if any other
info is missing. First time submitting a ticket :)
