[Qemu-devel] [PATCH] Call configure automatically when needed

[Qemu-devel] [PATCH] Call configure automatically when needed

[-- Attachment #1: Type: text/plain, Size: 183 bytes --]

Hello,

this patch calls configure automatically when configure
changed since the last time it was called.

If configure was never called, the user is told to do so.

Regards
Stefan

I have a truly marvellous patch that fixes the bug which this
signature is too narrow to contain.
