* EXPR_COMPAT should imply -e, since there is no way to specify it otherwise,wollman2002-05-112-1/+18

* The response to my POSIX interpretation request says that `expr'wollman2002-05-102-46/+88
| | | | | | is required to be oblivious to overflow and to use the data type `long'. (Division by zero is undefined in ISO C so it's still OK to check for it here.) Add a new `-e' flag to get the old, more useful behavior.

* Make expr POSIX-compliant, and fix some bugs. Specifically:wollman2002-03-222-104/+215
| | | | | | | | | | | | | - expr must conform to the Utility Syntax Guidelines, so use getopt() to eat the (non-existent) options. - Use the Standard type intmax_t for arithmetic. - If an argument cannot be *completely* converted to an integer, then it is a string. Additionally make some style cleanups near the modified lines. This utility is still not completely style-compliant.
