swig-3.0.7 for xapian-bindings to tcl

[Eric Lindblad]

I recently wrote a post on installing "Git for Windows" on a legacy XP SP3 Home box.

http://nurmi-labs.blogspot.com/2016/11/git.html

I added some missing files from the MSYS2 packages which were removed for the downloadable
"Git for Windows" installer and a compiler and some additional libraries.

For other utilities (bison, flex, info, m4, make, and csh/tcsh), and code I would compile,
I setup an extra directory tree as C:\MSYS2 and used an /etc/fstab mount point for that
directory mounted on /usr/local; wanting to distinguish between the basic "Git for Windows"
plus compiler and libraries directory tree which was in C:\Programmer\Git; these utilities
and shells being available from the appropriate i686 or the x86_64 webpages.

"Git for Windows" shipped with a Perl compiled for the msys environment, not the mingw-w64-i686 environment which the Tcl/TK it shipped was compiled for; Python and Python3 compiled for the 
mingw-w64-i686 environment are separately available as packages from the appropriate i686 or the
x86_64 webpages.

In the last section of my post swig is mentioned, and my questions are 1) whether crypt is
significant to allocate for, the "Git for Windows" shipped libcrypt 1.3-1 being compiled
for the msys environment - obviously one would need to add the dev package - for swig to
be compiled for use by xapian-bindings, and 2) the subject about gethostbyname and socket
found in the below output seems to warrant some clarification pertaining to the MSYS2 and/or
MinGW environments, and a swig compiled for use by xapian-bindings?

The dlopen issue I believe is POSIX and therefore not relevant to a mingw-w64-i686
(or mingw-w64-x86_64) environment; and furthermore -lieee returns 'yes' on GNU/Linux.

I should say that I am unconcerned whether potential responses pertain to 1.4.1 stable
or to 1.2.x old stable series.
