I know this will be going back a bit, but I have a problem with
compiling some code with ghc-5.04.3.  The same code goes through
ghc-6.2 with no problems, and until recently there were no problems
with ghc-5.04.3 either.  But a recent code change has caused the
following warning messages from ghc-5.04.3:

still has jump to fast entry point:
r4HK_entry:
        leal    12(%ebp), %eax
        cmpl    84(%ebx), %eax
        jbe     .L55
        movl    $r4HK_closure, %esi
        movl    -4(%ebx), %eax
.L56:
        jmp     *%eax
.L55:
        movl    4(%ebp), %esi
        addl    $12, %ebp
        movl    $r4HK_fast2, %eax
        jmp     .L56

There are about 350kb of very similar messages:

    still has jump to fast entry point:
    r3R_entry:
    still has jump to fast entry point:
    s4K3_entry:

and so on.

Does anyone have any idea what these mean, and how I might go about
fixing them?  Although they are only warnings, I'd like my software
to continue to be portable to older versions of ghc if possible.

Regards,
    Malcolm
