This one is slightly problematic, if an application
choose to allocate more room for its error buffer than
the recommanded JMSG_LENGTH_MAX the error message will
get truncated.
There should be no loss of functionnality and I'm not
aware of any app doing that.

cmapcomment is a local array, we can use sizeof.
