As I've written before: ca65 will only handle numerical expressions without
attributes. So it cannot distinguish between the values -1 and $FFFFFFFF (for
up to 32 bit host machines). While truncating

        val     = -1
        lda     #val

is acceptable,

        val     = $FFFFFFFF
        lda     #val

is not, because it may hide errors in the code.
