Strange, I'm not able to reproduce your findings. I did found
something rather odd though. I thought MSVC, ICL and GCC would
produce the same files, but for some reason a GCC compile creates
slightly smaller files. Looks like there is some GCC-specific code
that influences compression ratio? I haven't noticed that in any of
the tests I did before. GCC is a bit slower, but nowhere near 1.7x<br>

Results are here:

These results are from an MinGW compile (GCC 4.6.1 AFAIK), MSVC 2012
and ICL 13 compiles of FLAC 1.3.0 without any modifications. These
are all 32-bit executables run on a 64-bit Windows 7 system. The
graphs show encoding and decoding performance on Lord of the Rings:
The Two Towers (The Complete Recordings) in 44/16 and 48/24, and
Nine Inch Nails' The Slip in 44/16 and 96/24. See the graph titles.<br>
