: I too see the same executable size. My guess was that this is caused
: by the toolchain setup, the pagesize setting for target seems to be
: 64K, unless I am reading it wrong (contrib/binutils/bfd/elf32-mips.c
: ELF_MAXPAGESIZE)

: Don't know if there are any other knobs to control this setting.

Hmmmm, I'll take a look at this as my time permits...  I'm not sure if
it is the page size or something else, but I'll look into it...

I'm seeing similar results too now that I'm looking closely at
things.  It also explains why my root is like 290MB instead of 192MB
that my x86 trees are...

Of course, I'm gratified that people are complaining about problems
like this.  It isn't the sort of thing you gripe about if you are just
casually dabbling with the port :)
