Maybe, maybe not, but just changing that #define won't have the effect
you want, since there's a bit of machine-dependent code which needs to
be whacked, as well.

In PR 1891 (see I
proposed a set of diffs to make having a variable-sied and larger
message buffer easier.  They don't actually make message buffer size a
configurable option on the x86, but it's pretty clear looking at the
diffs how to make the message buffer larger.

Anyway, it might be an interesting starting point for you.
