In configure.ac, writing `xxx' (note that it is different quotation marks) will break the highlighting after this expression. I presume it stems from that Vim does not recognize that they should match each other.

This syntax file currently has no maintainer.
A change from @jamessan is mentioned in the header about paren matching.

The pattern

`xxx'

is how quotation marks work in M4. In Autoconf M4 quotes are changed to [] instead.

So the syntax file is working as expected here.

I think that issue can be closed @chrisbra
