Fix some compiler warnings
fix spelling.
Build fix for NetBSD and other systems where /bin/sh isn't bash

Fixed by explicitly using /bin/bash. Removing bash-isms would also
work. But /bin/sh is bash on most developers' systems, so using that
shell explicitly seems like it's less likely to break in the future.
Clarify legacy/current version info
Removed bash dependency in test/run_tests.sh and updated for NetBSD.

Makes 'nmake install' work.

In BUILDING.WIN32, the following line exists:

  nmake install

This doesn't work because the install targets never get built because of
the code:

  IF(NOT WIN32)
    INSTALL(...)
    ...
  ENDIF()

in several CMakeLists.txt files. There's no reason to disallow INSTALL
on Windows, even if most developers (who use devenv on its own) will
never use it.
json_reformat should link against libm

This is specific to qnx.
