- Subject: [PATCH] configure.ac: Also quote '$' in tbaseargs
Hi,
While working on some GDB changes I have stumbled across this, which
looks like a buglet in the top-level configure. Perhaps a three-way merge
error from the past. Unfortunately there is nothing in ChangeLog that
would indicate when these bits were introduced.
We have these two variables, $baseargs and $tbaseargs, that we handle
almost identically, except some bits are omitted from $tbaseargs only,
based on $skip_targ. However, at the point we decide to quote '$' in any
of the options collected we only do so for $baseargs. As a result, '$'
won't be escaped correctly in $tbaseargs and will break in sub-makes used
for the target. Have I missed anything?
If not, then here's an obvious fix. Found by inspection, I don't have a
test case handy. OK to apply?

* configure.ac: Also quote '$' in tbaseargs.
* configure: Regenerate.
