Thx Dave for suggestion, but Loic Grein (member of the list) told me
that your patch should work fine both on linux and cygwin.
I tried and it work fine.
Thanks a lot to everybody for your help.
Bye

Thanks a lot. Your solution work fine.
The problem now is that I should change the Makefile in order to have
two different behaviour in CYGWIN and linux.
Actually, if I haven't messed up, the workaround method using -r should be
fine for linux too - have you tried it?
The solutions are:
1. use if statements in order to execute different statements on linux
and cygwin. The question now is how I can do that. I mean what is the
variable I have to check with ifdef?
If you actually /needed/ to know, you could find out by $(shell uname) or
some similar variant, but I think the solution I gave should work fine on
linux and cygwin without needing to do anything different between the two.
2. Install binutils cross and set target i686-pc-linux. In this way I
have to change only the name of tools used to compile and link. But I do
not know how to do that. Could someone suggest me a link?
Oh, it'll be easier to just show you how. (Bulding a cross-compiler can be
ever so tricky, but building cross binutils is almost always a breeze):
Step 1: Download and untar the sources, create a directory for building in.
cd /tmp
wget http://tinyurl.com/y7a7hu
tar xfvj binutils-2.17.tar.bz2
mkdir obj
Step 2: Configure, build and install the sources.
cd obj
../binutils-2.17/configure -v --prefix=/usr/local \
--target=i686-pc-linux 2>&1 | tee conf.log
make all 2>&1 | tee build.log
make install 2>&1 | tee install.log
[optional] make -k check 2>&1 | tee check.log
Step 3: Tidy up.
cd ..
rm -rf obj binutils-2.17
Now all you need to do is make sure you've got /usr/local/bin in your $PATH,
and away you go; set AS to i686-pc-linux-as and LD to i686-pc-linux-ld in your
makefile.
please cc my address since I am not subscribed at the list
I remembered this time!
cheers,
