- Update to 2.14.1.6:
* Fixed version numbers in two cases in CHANGES that referred
to the 2.14.2.x instead of 2.14.1.x.
* Rename MINGW Makefile variable (a holdover from MINGW32_NT-5.0)
to OSNAME.
* Fixed FUNCPTR typedef in hist.c to fix deprecated compiler warnings.
* Fixed when USE_READLINE, READLINE_LIB, READLINE_EXTRAS, and
READLINE_INCLUDE are set to empty (disable use of the GNU-readline
facility).
* Fix cases of spaces before tabs in Makefile and Makefile.simple.
* Fixed obsolete references to the atoz() in LIBRARY to use the
correct internal function name of str2z().
* Fixed obsolete references to the atoq() in LIBRARY to use the
correct internal function name of str2q().
* Document in help/unexpected that * operator has has a higher
precedence than << in calc, which differs from C.
