Bugzilla Bug 137953

Was installing K3B on a freshly-installed 2006.0 system, which deps on
transcode.
The emerge dies on a syntax error (condensed here for clarity, full log will be
attached to this report):

This occured after I recently synced and built autoconf-2.59d (with success).
Tried downgrading to autoconf-2.59-r7 to see if that was the cause, but when I
tried re-emerging transcode afterwards, I encountered an error from aclocal
about a mismatched autoconf version.  Not sure if this is the fault of
transcode or autoconf (similar bug at bug #137921).

Thanks for reporting, this is indeed autoconf 2.59d's fault. I've now added a
patch to fix this (in the mean time autoconf is masked pending testing).

not a bug in autoconf-2.60

the patch you committed is correct, please send it upstream

autoconf now wraps AC_MSG_RESULT() in { } so this code:
v4l2=no AC_MSG_RESULT(...)

is turned into

v4l1=no { ... }
