Great that you included the complete config.log file! Thanks. This
was absolutely neccessary in order to recognize the actual problem.

The problem isn't just with gethostname() but also with other
functions, including select().

Various headers in /usr/include in the environment where you invoked
configure are incompatible with the MSYS headers in
/usr/i686-pc-msys/include in that same environment.

If this is not an error with your system and/or environment and you
want to build for MSYS then you actually want to cross-compile
libssh2, which is supported, but you have to be explicit about that
when invoking configure.

That could look like so: (This is just an example, you have to know
what is appropriate for your environment.)

./configure --host=i686-pc-msys

The key here is that your cross-compiler toolchain (MSYS gcc and
binutils) executables have an i686-pc-msys- filename prefix. So if
this is the correct prefix then you should be able to invoke e.g.
i686-pc-msys-gcc and i686-pc-msys-ld.
