Does any body know if there is ruby binary not greater than 1MB? It would be
better if smaller, because it would be implemented in space constraint
application like embedded linux system. TIA

There's another trick you can try -- before the ./configure, type
export CFLAGS="-Os -fomit-frame-pointer"
This will optimize for space rather than speed and eliminate frame pointers.

I think ruby *really* doesn't like to be built with optimizations. I
believe the garbage collector in particular has problems with it.

It's not just that...

config.log led me to try this:
$ gcc -Os -fomit-frame-pointer --disable-frame-address test.c
cc1: error: unrecognised command line option "-fdisable-frame-address"
Is it just my build of GCC (4.0.3)?

Me too. Mine's an Ubuntu Dapper install on a P4, gcc version 4.0.3 (Ubuntu 4.0.3-1ubuntu5).
Out of interest, what executable size do you get with that, before and after stripping?

Shouldn't that be:

$ ./configure --disable-frame-address
?

1. As far as I know, you don't need "-fdisable-frame-address". Mine is
working fine without it.
2. gcc 4.0.3 "should" work, but most versions of gcc 4.0 had some things
b0rk3d and 4.1 is in much better shape. I'm awaiting word from Gentoo
Central on when and how to upgrade to gcc 4.2 -- since almost everything
in Gentoo is compiled from source, a compiler change is a very big deal
in some cases.

So it looks like -O2 is a good bit larger than -Os. What I don't know is
the speed penalty, or what yours will do if you substitute
"-march=pentium4" for my "-march=athlon-tbird". My recollection is that
one of the gimmicks that enables -Os to generate smaller code is
elimination of 4-byte and 8-byte alignment adjustments whenever
possible, which would be a severe performance hit on floating-point work
but probably not in a Ruby interpreter.
I don't plan to benchmark any of this, mostly because I'm interested in
the other extreme -- waste as much RAM as you need and try all the
compiler optimizations to make the inner interpreter as fast as
possible.
