jdolecek 3a4441e3d4 reimplement expr using lexical parser generated by yacc ... highlights: * / is treated correctly depending upon context (addresses PR # 10995) * use 64 bit arithmetic, so expr is able to process integer values from -(2**63) to (2**63 - 1) * checks for integer over- & underflows added * error messages improved, more error checking added add AUTHOR section to manpage add BUGS section, and mention possible drawbacks with other expr implementations XXX the old expr treated empty string in arithmetic expressions as if it was 0 XXX this behaviour has been retained		2000-09-19 17:20:00 +00:00
