Thanks to Raphael Kubo da Costa <rakuco@FreeBSD.org> for the patch.
[01b77111e5]: Small fixes relating to this bug. In particular, the package name
mapping was not being distributed, and there were some small problems with what
the mappings were and how they were applied. Also prevented external URLs from
ending with a '.'; that's vanishingly rare...
Bump tcltest version to 2.3.6 (should have been done just before the 8.5.15 release, just as in Tcl 8.6.1). 
Don't fix eol-style for Makefile.in in "make dist", if the file system is case-insensitive/case-preserving.

Windows dll's should be executable.
Put extern "C" guards around all stub table struct definitions, so it is usable for C++ compilers as well without the danger of modifying the calling convention. 
For tclDecls.h it was no problem, because tcl.h already contains those guards. But for the other *Decls.h files (e.g. tclTomMathDecls.h) it was not correct.

Fix [5425f2c082]: [fconfigure -error] breaks the background processing of a pending [socket -async].
socket-14.6 only makes sense where both, IPv4 and IPv6 are supported.
[528717] Slight rewording to clarify what the evaluation steps are.
Grammar check...
Don't leak getaddrinfo() results
Map WSAEWOULDBLOCK to EWOULDBLOCK. Suggested by Reinhard Max.
