Subject: configure: quote command line arguments in config.status
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=835af8990c5ef4679a0cc44f0ee2582cfccbfc8d;p=qmiga%2Fqemu.git

configure: quote command line arguments in config.status

Make config.status generation a bit more robust.  (The quote_sh
function will also be reused to parse configure's command line
arguments in an external script driven by Meson build option
introspection).
