Preprocessed files compiles with GCC 3.4.0 and GCC 4.4.1. I added them as an

Can you check if the same preprocessed source for deflate.c (the deflate.i file
obtained with --save-temps) compiles fine with both 3.4.0 and 4.4.1? If so,
please attach it together with the deflate.s files produced by the

The problematic source code is deflate.c from libz.
CFLAGS=-O3 -DUSE_MMAP -m68060 -fomit-frame-pointer
When I compile all source code with GCC 4.4.1, I get slow minigzip binary.

This slowdown is because of libz. When I use minigzip from libz package to
compress data, I get the same slowdown with GCC 4.4.1. Maybe someone will try
to fix it?
