When evaluating an arithmetical expression, for example inside $(()),

2019-02-20T23:59:17Z

never do substitution (neither parameter, nor command, nor arithmetic, nor tilde substitution) on the values of any variables encountered inside the expression, but do recursively perform arithmetical evaluation of subexpressions as required. This makes behaviour more consistent, without hindering any behaviour promised in the manual page. A quirk originally reported by Andy Chu was that in the past, when encountering an array index, the shell would not only do evaluation, but also substitution on the array index, even though substitution would not be done on the expression in general. tobias@ contributed to initial efforts of understanding the quirk. patch tested in a bulk build by naddy@ "please commit" deraadt@

Support 64 bit integers on 32 bit architectures.

No binary change on amd64 and there should be no differences on any other 64 bit architecture either (because long = int64_t). ok cheloha, tb

rename global "e" to genv to avoid accidental shadowing and aliasing.
