[Qemu-devel] [PATCH] config-host.mak: escape configure arguments |
Date: |
Sat, 5 Oct 2013 15:41:32 +0100 |
Escape single quotes and newlines when writing configure arguments
to config-host.mak. This is necessary to allow correct regeneration
by re-executing configure in a shell when config-host.mak becomes
out-of-date.
