Fix "Under source code control" date for new version.h file. Sorted the order of symbols printed by "make env". Test if <stdbool.h> exists and set HAVE_STDBOOL_H accordingly in have_stdbool.h. Added HAVE_STDBOOL_H to allow one to force this value. Added "bool.h" include file to support use of boolean symbols, true and false for pre-c99 C compilers. The "bool.h" include file defines TRUE as true, FALSE as false, and BOOL as bool: for backward compatibility. The sign in a ZVALUE is now of type SIGN, whcih is either SB32 when CALC2_COMPAT is defined, or a bool. Replaced in C source, TRUE with true, FALSE with false, and BOOL with bool.
