[Haskell-cafe] Re: [haskell] ANNOUNCE: HNOP 0.1

OK, after going through this several times, here's what I've found:

1) The Debian linux build of haskell produces large executables.
2) The generic x86 binary distribution produces smallish executables
    (383765 bytes; still kind of large; stripped it's 191584 bytes).
3) I removed my entire source distribution, and recompiled from scratch with 
this build.mk file:

SRC_HC_OPTS     = -H64m -O2
GhcLibHcOpts    = -O2 -fgenerics
SplitObjs       = YES

I did an "autoreconf; configure; make; make install" and then recompiled hnop 
from scratch.  I got large executables (2838528 bytes unstripped, 1540072 stripped).

I'm at a loss here.  Somehow, the SplitObjs option doesn't seem to be doing the 
job.  Any suggestions would be appreciated.
