 [code omitted]
4.2 has some known deficiencies in its handling of void. The one you bring
up (catch is a function returning void, tch is of type pointer to function
returning void) is one of these. 4.3BSD cc fixes these bugs and results in
consistent handling of void. 4.3 should be available Real Soon Now.

Hope the workaround doesn't hurt too bad...

Nope, I didn't say nothing. Just random noise.
