SubjectRE: Compile warning in 2.5.66-bk latest
Date
Hi Andrew:

It's probably another change set in the file (J_EXPECT_JH).

I don't have gcc 3.2 installed so I could not verify, but maybe the
following patch could fix it.

Maybe a better fix is to define all J_EXPECTxxx as sth like:

#define J_EXPECT(expr, why, params...) __journal_expect(expr, why, ##
params)

as why is always needed.
